The Mass and Angular Momentum Relation of Eclipsing Binaries

Abstract

With a total 3780 eclipsing binary system in the Catalogue of Approximate Photometric and Absolute Elements of Eclipsing Variable Stars by Svechnikov & Kuznetsova (1990), the empirical relations between the systemic mass and orbital angular momentum have been examined. It is found that, during the its evolution, the total orbital angular momentum of the eclipsing binary system is not conserved. It decreases gradually, though not at a constant rate, until the system becomes into contact from initially detached via semi-detached system.
