Abstract
Three active binaries of the RS CVn class with short period (SV Cam) and intermediate period (VV Mon and SS Boo) are studied by applying the statistical procedure of Busso and Scaltriti (1983) and the analytical method of Busso et al. (1984; Paper I) to a collection of photometric light curves extending for some years. The behaviour of the wave distortion for the studied systems can be reproduced fairly well by the model and allows to determine relevant parameters, such as the angular velocity at the equator, the rate of differential rotation, the rate of latitude shear of spots and the latitude of spots at formation. Though based on a small sample of objects, the results seem to indicate that short-period and intermediate-period binaries can behave quite similarly for what concerns spot cycles.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
