Abstract (from CDS):

We present optical photometry of the short-period eclipsing RS CVn system WY Cancri for the years 1988-1997. For each light curve, we model the distortion waves in order to study the behavior of starspots in this system. After removing the spot effects from the light curves, we model the cleaned data to obtain system parameters. We also note changes in the luminosity of the primary star that are not explained by the spot variation.
