RX Cas revisited
Abstract:Between 1969 and 1993 a number of UBVR light curves of the long-period W Ser-type interacting binary RX Cas (Porb=32.328 days) were obtained at Tallinn Observatory. The results of earlier observations, the interpretation of the light curves as well as the investigation of the nature of invisible primary component, intrinsic variability and its period (Pintr=516.06 days) were summarized by Kalv (and also discussed by Martynov). In recent years, new solutions of the radial velocity curves as well as of the synthetic light curves of RX Cas have been obtained. This enables the physical parameters of the components to be determined more accurately and the rate of mass exchange between the components and the initial parameters of the progenitor to be estimated with better precision.
