1. Accretion disks in long-period Algols: RX Geminorum Creator: Olson, Edward C. and Etzel, Paul B. Format: bez média and svazek Type: model:article and TEXT Subject: accretion disk and Hα emission profiles Language: Czech Description: We describe multicolor photometric solutions of the long-period Algol RX Geminorum, accretion disk kinematics deduced from phase-dependent radial velocity observations of disk Hα emission and fits to Hα profiles using a non-LTE disk model.
