The cycle length of the dwarf nova EM Cyg undergoes season-to-season changes which may be interpreted by changes of the accretion rate caused by a solar-type activity of the secondary star. The mean brightness of EM Cyg varies with a cycle of ≈ 300

Exactly 25 years ago, Santiago Tapia has detected circular and linear polarization of AM Her varying with the same period as the photometric and spectral characteristics. This had lead to a discovery of unprecedentedly exotic binary systems, in which
