ABSTRACT

        I was on the way to my high school French Oral exam in October 1965 when I decided that I wanted to begin a search for comets.  Although I began the search on December 17 that year, it was not until 1984-- 19 years or 917 hours at the eyepiece later-- that I discovered my first comet.  Twenty-one finds later, I still feel that comets are more than just targets to be catalogued. 

            Thanks in part to one co-discoveries, Shoemaker-Levy 9, we know more about the role that comet collisions have played in the origin and evolution of life on this planet.  With the evolution of Pan-StARRS, the future of visual comet finding will soon be relegated to the history of this important field of endeavor.

I am still searching for comets both visually and with an automated CCD program.   This talk will be about my observing career and how my childhood fascination with the night sky led to a highly satisfying time under the night sky.

ABSTRACT

Science, the most important tool for understanding the nature has become a part of our. So that, science and technology determine our life style without our notice. On the other hand, there is a large gap between man on the street and science. Popular science publishing is one of the most important bridges between science and the society. But, the importance of popular science publishing is not well understood in our country. To be able to convey science to our people, the importance of popular science publishing should be understood. TUBITAKs (Turkish Scientific and Technical Research Council) popular science magazine Bilim ve Teknik is trying to build the science culture that our society needs. Beside popular science publishing, we consider the popular science activities as important tools. Here, the National Sky Observing Festival is the first product of this approach.

ABSTRACT

Pulsations of the solar diameter observed about half a century ago, are thought to result from big  scale motions in the solar photosphere.  These motions are highly variable in space and time and change amplitude according to the physical aspects of turbulence, magnetic field and rotation. Standard solar models (SSM) obtained directly from the  integration of the linear differential equations describing these motions with respect to turbulence, agree very well with the observed solar resonant periods. On the other hand, inclusion of rotation and magnetic field in the SSM split the frequencies symmetrically.

Similar to the p-modes encountered in the Earth quake waves, the observed solar pulsations contain quantitative information about the structure of the solar photosphere. Therefore, the geophysical inverse model is employed also in Helio-seismology in order to estimate density, temperature and pressure inside the Sun, from the observed acoustic p-modes of 5 minutes periodicity. In this work examples obtained by the two methods will be presented and compared both with the standard solar models and observations.

SUMMARY

Comparing on RX J185635-3754 Neutron Star on optical and X-ray for 1 view with other rays taken from satallites and researching on where it borns calculating excess flux of RX J1856 optical flux (49eV) to x-ray blacbody flux (57eV) discussing.DATAS FROM SATALLITES:*RASS-Cnt Broad, PSPC 2.0 Deg-Inten, Old PSPC (2 deg), COBE DIRBE, IRAS 12 micron, IRAS 100 micron,1420 Mhz (Bonn) and GB6 (4850 MHz) are taken at 1view,By using engtral we can calculate the areas under graphics; Excess flux=flux(upper)-flux(lower)  

The difference flux=(observed flux) – (x-rays for black body line continues)

The upper line (observed) in between l1-l2 wavelength bands shows total flux from the target The upper line (X-rays for black body line continues) in between l1-l2 wavelength bands shows total flux from a black body, Excess flux of optical spectral energy distribution flux to x-ray for blackbody energy distribution flux (57eV)  [Between F303 HSTU and F606 HSTV]

Corpared to binary X-ray pulsars,AXPs have lower luminosities and exhisits narrow distiribution of periods.Unlike young radio pulsars ,AXPs have rather long periods and appear to be radio quiet.To understanding there differences is to try and identfy the energy source that powers the x-ray emmision. It is quite clear that this energy cant be provided by  rotation. Their rotating speed is too more, after the explosion the conductive liquid matter inside the star causes 1*1012 Gauss Magnetic Field that makes the star like a dynamoMagnetars: X-ray luminosities could be powered by magnetic field.Residual thermal energy (if it is correct the envolope of the star must consist light elements such as hyrdogen and helium).The emission is powered by magnetic field deray then a value of B ³ 1016 G is requried unlies nonstandart deray processes are invoked. As AXPs models its alone, SGR models its magnetar, SGR and AXP common properties  its alone and in AXP and  SGR  it is106 year old.As AXP DNT SGR RQNSS its propeller spindown with high spindown rates larger than 10-12 rad/s2 can indeed   be expected for neutron stars with conventinal 1012 Gauss fields under the typical   spindown torques for certain phases of accreting sources .   Propeller torques depend on the magnetic moment of the neutron star and on  the rate of mass in flow.

ABSTRACT

Europen Union 6th Framework Programme (FP6) thematic priority of Aeronautics and Space in the context of the Advisory Council for Aeronautics Research in Europe - ACARE and European Strategy for Space shows that Research Technology Development must be stronger and aiming to reach higher levels of technological excellence. Development in the air transportation in the period of 10-15 years will cause the shorter distances and easier transportation between two places. In addition the development in the air transportation can cause some negative impacts. Therefore Europen Union decides to include improving the environmental impact, improving aircraft safety and security, increasing operational capacity and safety of the air transport system in FP6.  Europen Union  7th Framework Programme (FP7) will cover aeronautics and space in two different thematic areas.

TV CorvI: The personal story of the dIscovery of a HIgh GalactIc LatItude CataclysmIc VarIable

ABSTRACT

            Clyde Tombaugh, discoverer of Pluto and a lifelong AAVSO friend, lived in Las Cruces for the last 50 years of his life; his family still lives here. During his search for trans-Saturnian planets he discovered what he thought was a nova in outburst March 23, 1931. Although he reported it to his superior at the time, news of the discovery remained buried in the plate archive at Lowell Observatory until I found it while doing research for his biography. A search of the plate archives at Harvard subsequently revealed 9 other outbursts of what was apparently a cataclysmic variable of high galactic latitude. Now named TV Corvi, the star was first visually observed in outburst on March 23, 1990.

            On February 2, 2005, I caught the star rising in the southeast and climbing rapidly in magnitude. The movie consists of several images taken throughout that night.

ABSTRACT

The idea of watching a point of light brighten and fade over a specific period of time is not always an "easy sell"-- there are some very good amateur astronomers who have embraced the planets, comets, and deep sky observing while leaving variables alone. Like fine wines, variable star observing can be an aquired taste. Fortunately, over the decades, some people have dedicated their careers and lives to making the field accessible to the larger community of lovers of the stars. This presentation celebrates the work of two of these championbs-- William Tyler Olcott and Janet Mattei, two mentors who transformed variable star observing into a field that touches the hearts of their generations. They both combined knowledge and enthusiasm for variables with an uncanny way of reaching out to people. Variable stars would not be the field it is today were it not for the efforts of these very special astronomers.

Abstract

Today it is not possible for people, who live in or near cities, to have a view of the universe. Since the population of the urban areas increased, outdoor illumination has been considered to be necessary which now ends up with the consequences of urban sky glow.  The misuse of light doesnt increase nighttime security. The excess light in the sky cause light pollution and it doesnt only obstruct the night sky view but also threatens the nature.

Since astronomic studies should be done away from air pollution and urban sky glow resources, the sky glow which illuminates the night sky is a threat to amateur and professional astronomy.

Understanding the concept of light pollution is very important to control it. Some of the precautions to be considered are using night lighting only when it is necessary, directing the light downward in order to prevent illuminating the sky, using low pressure sodium light sources if color rendering index is not very important and avoiding development near existing observatories.

Abstract

UBV light curves of AM Leo which is a short period W UMa type contact binary were obtained at Ankara University Observatory in 2005 and analyzed. Preliminary solutions of physical parameters of the system were carried out by using Binary Maker and Nightfall lightcurve analysis programs. Two different solutions were determined by adjusting and by fixing the mass ratio (q = 2.51). The solutions describe that AM Leo system has a W sub-type overcontact configuration with an inclination of ~ 82  and a very small temperature differences of the components.

Abstract

            The American Association of Variable Star Observers (AAVSO) is a worldwide, nonprofit, scientific and educational organization of amateur and professional astronomers who are interested in variable stars. Its purpose is to coordinate, collect, evaluate, analyze, publish, and archive variable star observations made largely by amateur astronomers, and to make these observations available to professional astronomers, researchers, and educators. The AAVSO was founded in 1911 at Harvard College Observatory to coordinate variable star observations made largely by amateur astronomers. In 1954, the AAVSO became an independent, private research organization. Today with members in more than 40 countries, over 10 million observations to date, and headquarters in Cambridge, Massachusetts, USA, it is the worlds largest association of variable star observers in existence. Membership in the AAVSO is open to anyone interested in variable stars and in contributing to the support of valuable research. Since professional astronomers have neither the time nor the telescopes needed to gather data on the brightness changes of thousands of variables, amateurs have been making a real and useful contribution to science by observing variable stars and submitting their observations to the AAVSO International Database. Observations of most types of variable stars are coordinated and published by the Director and the technical staff at AAVSO headquarters. Observing for certain types of stars is coordinated outside of AAVSO headquarters, under the authority of the AAVSO director.

Abstract

6500 years ago, people wanted to discover nature because of fear and curiosity. People realized to connection between nature and universe. Then they started to think about them. So they took the first step for science. The best sample for that had lived people at Mesopotamia.

The first settled people who came from Persia to the South Mesopotamia at c.B.C. 4500. They were not speaking the Sumerian language and their ancestry not Sami. The Sumerian people started to live at the South Mesopotamia at c.B.C. 3500. But they had been attuned to nature very fast. Perhaps, this event was effecting of people who settled 1000 years ago.  

The Mesopotamia had been favorite land by a lot of civilization its geographical location and productive land. So, they had complex culture.

I have analyzed about universe / earth comprehension of Babylon, Sumerian and Kaldeli at B.C. 4500 – 540.

Abstract

Astronomy was one of the ancient part of the science known by humanbeing. On the otherhand Astroarcheology is working on the ancient construction & structure and explain the their situations & locations against to the Sun and the Moon. Besides, it benefits from the guidance of the geodesy and mythology while doing this. Because the Ancient Civilizations have equated the Nature with the God and have explained the nature events by considering on that acceptance. The most important astroarcheology areas on the earth are listed below:

Pyramids and Towers: Caracol, Chitchen Itza, Mexico

Ground Trace: Nazca, Peru

Megalytic Area: Stonehenge, Carnac, Newgrange  

The Major Characteristic of Astroarcheology is that becuase of the Ancient Civilizations Valuable Observations, easly able to be informed about the occured changes in the Space. Therefore, Astroarcheology has rapidly been develop since 1960.

There are too many Astroarcheological area in Turkey but most of them has been kept with extreme carelessness. Some of the astroarcheological areas on our land:

Abstract

It might be surprising to many people that astronomy is unique among the sciences in which amateurs can and do play an important role. Amateur astronomers frequently and increasingly make valuable contributions to astronomical research. While professionals are typically absorbed in conducting specialized research, amateurs can go for time-consuming activities such as comet and asteroid hunting, variable star observing, novae and supernovae searching, making lunar and planetary observations and more! In addition to that, observing time at the major observatories is limited and it is not that easy to come by. This leaves open areas in which a dedicated amateur can make a significant contribution. Some of the tasks only professional astronomers were able to perform in most of the 20th century, are being done by amateurs today almost to the same degree as professionals. Commercially available affordable equipments, not having observing time restriction as in professional observatories and being scattered around the globe geographically are some of the factors that are making the amateur contributions soar. It is what we call Backyard Astronomy after all.

ABSTRACT

In this study, considering the Sun as an incompressible fluid, our objective was to investigate the variation of the physical changes in the 30 % outermost convective solar layer with the use equations of magneto-hydrodynamics (MHD) for both linear and non-linear cases. Maple 8 was used for studying the changes in density, pressure, temperature and magnetic field with respect to time and radius. The first order perturbation approximation was used in MHD equations while we examine the linear case. For the non linear case, the Sun was accepted as a spherically symmetric star and the analytical solutions of these equations were obtained. Hydrostatics equilibrium state was taken as a Standard Solar Model (SSM) excluding both rotation and magnetic field.

Abstract

The diameter of an asteroid can only be measured by the occultations. In order to observe an occultation of a star by the asteroid, the first step is to determine the time of its passage in front of a star on the sky. This time can be calculated using WinOccult Ver. 3.0 software. In this method the duration of the occultation of a star is measured. Then the diameter of the asteroid is calculated using the its distance and the orbital velocity. Occultation technique gives very precise results for the spherical shape asteroids. Results obtained from the occultation method can be used the calibration of the other indirect methods such as thermal radiometry.

 

Astronomy and cultural heritage

ABSTRACT

In the entire world there are proofs of astronomical culture, from the famous Stonehenge or Carnac, up to tapestries (Bayeux), heraldic symbols, sundials, old observatories or manuscripts. All of them preserve in stone, wood, ceramics, metal or paper the knowledge gathered throughout the centuries concerning the sky, the cosmos.

They are spread all over the world. Sometimes they are well catalogued, researched or preserved. Nevertheless, very often they are very little known and very badly preserved, sometimes about to disappear. You want to find out where there is a sundial from a certain epoch and you do not know how. You want to know when some phenomena were recorded for the first time and researches to this effect are difficult. You want to support the restoration of a sanctuary, also used for astronomical purposes, and you do not have enough proofs to motivate the sometimes very high expenses required by such an operation.

A data bank in which all this information should be gathered, an electronic library of international size, would be the exact thing to facilitate research, to support the conservation of the art, science and history monuments, which together make up the thesaurus of civilization on this planet.

This is shortly the reason why a new working group The Archaeoastronomical Heritage (http://www.archeoastronomy.org/) was set up. Everyone interested in identifying and preserving this rich heritage is invited to contribute to its activity.

Abstract

The topic of this project is naked-eye astronomy. One of the most popular methods of unaided observations is the Argelander method. During the application of this method, bright variable stars which have a short period and  high variability amplitude of light curve are selected, especially the Algol type. Aurora and meteor observations are also other popular naked-eye astronomy subjects. Because of its location of Turkey, unfortunately  auroras can not be observed by Turkish amateur astronomers wheras variable stars and shooting stars observations are performed at the Ankara University Observatory.

Key words: naked-eye astronomy, variable stars, Argelander method, meteors

The periodic movements of  the stars have been examined carefully with a software program named Starry Night Pro that gives the accurate locations of  the stars in picture.

Using the pictures of stars of a certain time and date, I have found the systematic variation in the location of stars. I have transformed the variation into equation form. This equation helps us to determine the time if  the date is given and vice versa.

This systematic variation is caused of the difference between the real and accepted rotation period of the Earth. In other words its accepted that the earth spins around its axis once in 24 hours but in fact the real period is 23 hours 56 minutes.

This time difference causes a deviation in the location of stars. Measuring the deviations for many times helped us to find the relationship between time and date.

Abstract

With growing techniques in observational tools and techniques, astronomical observations are carried out in each area of electromagnetic spectrum. Radio astronomy is a technique, by which, radio waves emitting from astronomical objects are received, recorded, and assessed.

The first radio observations in Turkey were carried out in TUBITAK MAM(Marmara Research Center) on 1996-97, by MRT-2 (Marmara Radio Telescope-2) having 2m dish, which were bought from Kharov Radio Astronomy Institute with the help of UNIDO. Later on, this telescope was donated to Erciyes University, Astronomy and Space Sciences Department . With the Radio Telescope which was re-constructed with the help of the 5m dishes taken from Turkish Telecom in 2002, the neutral hydrogen observation in our galaxy are planning.

ABSTRACT

Problems in education are getting bigger and day after day reformer solutions are taking part in education ways. To improve peoples interests and abilities in Main Sciences a reformer solution having been prepared since a few years ago. That subject is about using movies in science. Combining Cinema and Education reveals impressive results. Also using cinema in Education of Astronomy and Space Sciences gives perfect results. Our goal is using the scenes have taken from movies that use astronomy and space subjects, suggesting a new kind of educating Astronomy and Space Sciences. A "Physics in Films" class at Central Florida University, taught by researchers Costas Efthimiou and Ralph Llewellyn, has drawn more than 2,000 students since its first offering in 2002. These educators firstly used the main physical laws. And they showed other scientists a new way of education. The subjects; understand the universe, life on the other planets, danger from space, and space travel in movies can be great sources to study Astronomy and Space Sciences. Critiques and reviews of those movies can improve students interests and abilities in Astronomy and Space Subjects. As a result we want to share that way of education with our colleagues.

ABSTRACT

A period study of double star AH Vir has been performed with published minimum times and new minimum times which obtained at Ankara University Observatoy. In order to designate the charactristic of period variation, an O-C graph formed. O-C graph shows a period increase with cyclic variation. Under the assumption of  conservation of  the total angular momentum, the period increase can be atrtributed to mass transfer from less massive to the massive one. Cyclic variation can be attributed to light-time effect due to presence of third body in the system. The related physical parameters derived in this assumption.

Keywords: AH Vir, eclipsing binary stars, period analysis.

Abstract

The astronomy departments of the universities in Turkey have made great effort in the last 50 years to increase the concern and sympathy of the public in the field of astronomy and in science as well. Publishing some periodicals and organizing summer schools are main activities among these. The staff and the students of the Astronomy Department of Ege University have assumed a leading role during the last 14 years and trained hundreds of people. 50% of the participants of the organized summer schools are between 18-50 years of age and this fact indicates that they are well able to continue their work themselves. Some of the people who followed these activities have started working on various topics with their own telescopes. Some of these works have already been published in various magazines.

ABSTRACT

The Solar eclipse is a magnificant natural event so that people can see maybe only once in their lifetimes if they do not move to another place. Our country will witness again a total solar eclipse on 29 March 2006 after the 11 August 1999 eclipse. This eclipse will be visible within a zone starting from western Mediterranean to eastern Black Sea regions during almost 4 minutes. On the other hand, TUBITAK National Observatory of Turkey lies within the zone of this totality. This work include the specifications of 29 March 2006 total solar eclipse, contact times, meteorological data, public organizations and observational techniques. Preparations have already begun in Antalya and at the National Observatory to utilize this rare fascinating event.

ABSTRACT

Although I didn't meet Janet until the last year of her life, we immediately became good friends-- not so much for her love of astronomy but for her almost equal passion for flowers.  As David showed her our observatory complex, I shared her amazement as she stopped over and over again to admire the diversity of natural flowers in our desert home, and she told me of her interest in doing a project-- some day-- relating her two loves of flowers and the universe.  In her honor, I offer a look at the amazing coincidences that atoms and Nature can come up with--  a dandelion on Earth and Scorpius in the sky, a flower blooming for only a day to remind us of a long-gone nova in Messier 80, and other tiny flower designs that mimic some of the vast structures of distant galaxies.

ABSTRACT

Ive been doing observations for four years with Meade ETX125 telescope. Up to now, Ive taken Astronomical League Lunar Club and Double Star Club certificates by doing Moon and Double Star observations. Currently Im observing Messier objects for the Messier Club certificate. At the same time, Im observing Bright Lunar Rays for ALPO and Variable stars for AAVSO. I do observations about three nights a week. My observation site is the observatory Ive built in my houses backyard, Green Island Observatory. The need for building the observatory has risen due to the difficulties faced with when carrying all the stuff each time needed for the observation. The observatory, which was built between the July 2004 and February 2005, is situated in Geitkale, Northern Cyprus. The observatory is formed from cylindrical concrete walls and a wooden dome situated on its top. The dome, which is mounted on a U-joist ray, is moved manually. Im planning to have a bigger aperture telescope and a CCD camera. In order to prevent the small vibrations caused by my movements while observing, j-bolts are fixed in an isolated concrete part in the centre of the floor. The telescope will be mounted on a pier, which will be set on j-bolts.

My future plans are, to get more educated by having the advanced university certificates in Astronomy and to develop observational experiences and to do observations to contribute the Astronomy.

Abstract

The number of amateur astronomers in Turkey is increasing rapidly in recent years. Many of them have their own telescopes equiped with detectors such as a CCD camera. We know that beautiful pictures are secured with these instruments. But it is now time to turn these hobies into scientific observations, mainly concetrating on variable stars. Our amateur astronomers should come together under a national association which helps its members with coordination of observations, with astronomical tools to be used in the reductions, and with assessing the accuracy of their observations. This national body should maintain a database for the benefit of  its  members and for the use of  professional astronomers.
