Abstract:
We present the analysis of new BV light curves for the active star
SV Cam applying the Roche model with spotted areas on the hotter primary
component. Two spots
at medium latitudes and covering about 14% of the stellar
surface were revealed. Both are ∼1000 K cooler than the surrounding photosphere.
The comparison with earlier
seasons (2000-2003) suggests that the spots probably evolved
in area longitude and latitude. Both tidal effect and activity cycle mechanisms
may be in action.
