K-type overcontact binaries.
Abstract
Photoelectric light curves were obtained of five K-type, very short period (no more than 0.3 days), contact binaries: CC Com, FG Sct, BI Vul, FS CrA, and VZ Psc. These were analyzed using the Wilson-Devinney code, and satisfactory results were obtained for all the systems except VZ Psc. Analysis revealed indications of subluminous regions, probably starspots, on the larger components of CC Com and BI Vul. These were modeled using a code by Binnendijk (1977) providing temperature and size estimates for the spots. Flarelike activity was seen on FS CrA.
