Mass transfer in ALGOLS and its implications to the mass transfer theory

Abstract

he average mass transfer rates in four Algol-type binary stars RZ Cas, TV Cas, SW Cyg and DI Peg are derived from their observed period changes in the light of alternate period change model. The results have been used to discuss the anomalies in the mass transfer theory, namely dynamical instability of the mass losing component and the conservation of orbital angular momentum during the mass transfer.
