SV Cam, an eclipsing binary containing a BY Draconis variable

Abstract

New photometric observations are presented of the short-period eclipsing binary system SV Cam. These, together with published data, are analysed and it is shown that the system is composed of a G3 V primary component slightly evolved above the main sequence and a K4 V secondary component which also exhibits BY Draconis-type variability. The extensive series of published times of minima indicate that the eclipsing pair orbit a third component with a period of 64 yr.
