Abstract:
New BVR light curves and times of minimum light for the short period
RS CVn system SV Cam were analysed to derive the physical parameters
of the system and the parameters of the third body orbit. The light
curves obtained at the TUEBITAK National Observatory during two nights
in 2000 show considerable asymmetry and night-to-night variations. The
analysis of the light curves is made using Djurasevic's inverse
problem method. The Roche model with spotted areas on the hotter
primary component yields a good fit to observations. The extensive
series of published photoelectric minima times indicate that the
eclipsing pair orbits around the common mass center of the triple
system with a period of 41.32yr.
