Variable Stars - DI Uma
Type ER Ursae Majoris-type Click for lightcurve ER Ursae Majoris-type subclass of UGSU dwarf novae stars typically spend a third of their time in super-outburst with a super-cycle of 20-50 days. Outside of super-outburst they typically pack in a rapid succession of normal outbursts. Amplitudes are smaller (around 3 mag.) than in other dwarf novae due to a higher mass transfer rate.
