Among the RS CVn stars showing solar-type activity, with spectral types ranging from F to K and total masses up to 4 M, there are two peculiar groups with period less than one day:a)agroup with components well inside their Roche lobes (Short-Period-Group, hereinafter SPG) and b) a group with their components in a thin or marginal degree of contact, with lightcurves of W UMa-W type (hereinafter WWG).
