Variable Stars - TY Psc
Type SU Ursae Majoris-type Click for lightcurve These are characterized by the presence of two types of outbursts called "normal" and "super- outbursts".  Normal, short outbursts are similar to those of UGSS stars, while super-outbursts are brighter by 2 magnitudes, are more than five times longer (wider), and occur several times less frequently. During super-outbursts the light curves show superposed periodic oscillations (super-humps), their periods being close to the orbital ones and amplitudes being about 0.2-0.3 magnitudes in V. Orbital periods are shorter than 0.1 days; companions are of dM spectral type. AAVSO Legacy Cataclysmic Variable Programme
