Just over one year ago, a small spacecraft called MOST began a month-long observing run on one of the most spectacular objects in Earth's skies, the beautiful Trapezium region at the heart of the Orion Nebula, M42. My collaborators and I applied for and received this observing time to survey variability in this young stellar cluster -- partly to study the eclipsing binary BM Ori (theta 01 Orionis B), but also to survey as many young stars that we were able to using the unique capabilities of MOST. Since then, I along with my collaborators -- our Director Arne H
The paper "Optical and X-ray Variability of the Peculiar Cataclysmic Variable FS Aurigae with a Magnetic and Freely Precessing White Dwarf" by Vitaly Neustroev and collaborators is now available on arXiv.org. The paper was co-authored by several AAVSO observers, and involves data taken during the 2010-2011 observing campaign.
The paper "Modern observations of Hubble's first-discovered Cepheid in M31" has been accepted for publication to PASP, and is now available on arXiv.org.
AAVSO Special Notice #258: Request for monitoring of SS Cygni in support of European VLBI radio observations
[Edited 2011 July 12 to indicate that the apertures and annuli are radii rather than diameters. -- M. Templeton, AAVSO]
Continued close monitoring of T Pyx requested
June 30, 2011: Since its outburst on 2011 April 14 (see AAVSO Alert Notice 436), the recurrent nova T Pyx has been very well monitored by visual and instrumental observers who can reach -32o. Thank you! Currently T Pyx is visual/V magnitude ~8.3.
Campaign to monitor the recurrent nova T Pyx throughout 2011 eruption
April 15, 2011: Further to AAVSO Alert Notice 436, a fast photometry observing campaign has been initiated by Dr. Bradley Schaefer (Louisiana State University) to monitor the recurrent nova T Pyxidis throughout its current eruption.
