Variable Stars

This website is dedicated to the study of variable stars. This website is not intended as a general introduction to variable stars so it has become a bit of an insiders website.

There a few projects that I am maintaining here:

1) a list of newly discovered and published but undesignated variables in the last three years of the electronic variable star publications: New Variables list

Information Bulletin on Variable Stars www.konkoly.hu/ibvs

Peremennye Zvyezdy (Russian Variable Stars journal) www.astronet.ru/db/varstars

Open European Journal on Variable Stars http://var.astro.cz/oejv/oejv.php?lang=en

Journal of the AAVSO http://www.aavso.org/publications/ejaavso/

The last version of this list is from 20-01-2008.

2) a list of eclipsing variables and other short periodic variables discovered in the ASAS project, that have not been investigated yet, but for which there are additional data

from the Northern Sky Variability Survey (NSVS). For these variables a period study and light curve should be very easy to make because this list contains the hyperlinks to both

data sources. When I started this list about two years ago, it contained 4411 variables.

I am now checking from my previous list (see 1) which ones have already been investigated. To my surprise, this is a list of just about 200 variables.

In this tempo it is going to take 20 years or so before all of these variables have been studied.

New eclipsing variables list contains the present list and will be updated shortly. I will take out the 200 or so that have already been studied.

3) Geschichte und Literatur des Lichtwechsels der veränderlichen Sterne.

Because this publication was not available in the scanned literature service from the NASA, I scanned my own copies and made them available here.

Go to the Geschichte und Literatur des Lichtwechsels der Veränderliche Sterne by Richard Prager page for more details.

4) I used to offer here also integrated databases for variables from the GCVS and other surveys, but as the search options in the CDS http://cdsweb.u-strasbg.fr/ have improved quite

a lot in the last two years (the ASAS database can be queried, the GCVS now includes the suspected variables etc) there was no need for these files anymore.
