1131 stars discovered as of Apr 25, 2013
The first ACV discovery in the project
Finally! A bright ACV variable star (median is nearly 10.4m) has been
discovered by Alexandr Ditkovsky recently.

Preliminarily, ASAS-3 data shows the amplitude of 10.37-10.47m with a period of 63.3 days. Due to peculiar physical properties of
these variables we can see a very distinctive light curve with a bump.
Available photometric data is quite clear with reasonable error value and covers full cycle many times, so the phased curve is quite complete and reliable at 63.3 days period.

Two new T Tauri stars in Taurus
T Tauri itself is the prototype for a class of very young stars, still in the process of gravitational contraction; that is, they have yet to evolve to reach the main sequence. Discovered stars are VSX J034605.3+292034 and a Weak-line T Tauri star VSX J050030.0+172359. Read more...

Six new close binary systems with O'Connell effect.
We introduce six new objects for which the presence of O’Connell effect in the light curve is clearly noted. All of them are short-periodic close binaries of EW type, except one: NSVS 3878776 is an interesting Beta Lyrae-like system. Read more...
