Var Psc

We recently released a significant update to the backend systems for the AAVSO website. While most of the bugs introduced by this update have been fixed, there may still be problems we haven't fixed. If you run into a problem, please email webmaster@aavso.org

Hi,

The suspected UG-variable Var Psc is not in the VSX. Is there more information known about this star? Has it been dropped as a probable dwarf nova?

There is a sequence for this star (and RZ Psc), made by Bruce Sumner :

Thanks,

Hi Eddy

Do you mean var Psc 2010? at 23h 04m 26s   +06° 25’ 45”, UG   11.5 – 21 CR.

If so, just type in var Psc 2010. It is in VSX but there is no sequence. I use a sequence by Mati Morel Chart 66-A00028.

Interestingly, when I searched WebObs, I found the star listed as SDSS J230425.87+062545.7 with 17 observations all by you.

Kind regards, Stephen [HSP]

Hi Stephen,

Yes, I have SDSS J230425.87+062545.7 (Var Psc 2010) on my observing list but Var Psc is another suspected CV. Here is a chart with the coordinates :

Hi again, Eddie. Thanks for the chart. It's a bit far north for me although I do observe AW Gem occasionally and that's +28.

I did a coordinate search in VSP and voilá, found  EQ J010959.2+280125

That is your star and it's listed in VSX under this name. There are 4 references in VSX.

Kind regards

Stephen

Hi again Stephen,

The reason I didn't find it is because I was searching in the list with cataclysmic variables.  I see that it's no longer a CV... The VSX gives non-cv. According Downes it's a F-type star.

Cheers,

Eddy

It's in the same field as the UXOR star RZ Psc, so why not estimate it at the same time?  You never know what Var Psc might get up to.  I have years of data on it, and it certainly isn't a flat line light curve.  Small amplitude variations maybe, but it's not steady.

Hi Gary,

The CRTS light curve shows about 0.1mag variations, so it is probably below the measurement level of most visual observers.  APASS gives (B-V) = 0.5, as did my USNO measurements, in agreement with the F-classification from Downes.  While estimating it because it is in the field of RZ Psc makes some sense, I would not make this a high priority estimate.  Perhaps some of the time-series folks who have looked at RZ Psc have higher time resolution datasets that could pin down whether this is a periodic variable, a chaotic one, or not variable at all.
