Fast Changing StarsThe quality of the lightcurves that can be obtained using AREO4 at RASO is obvious. It would be instructive to follow these stars for a number of consectutive cycles as there is a suggestion that the shape of each lightcurve is variable. GP AND - Period 0.078683 days
BL CAM - Period 0.039098 days
SZ LYN - Period 0.120535 days

The dwarf nova SS Cygni in outburst
SS Cygni is a cataclysmic variable star, of the dwarf nova class. Such variables are comprised of a close binary system with a white dwarf primary star and a red dwarf secondary star. Over time the main sequence star loses matter towards the primary, forming an accretion disk around it. The observed outbursts are believed to be the result of processes that arise in this disk.
