Abstract

The aim of the present paper is to present the analysis of light changes of four β Lyrae eclipsing systems (DO Cas, KR Cyg, V388 Cyg, and SV Cen) using the automated Fourier techniques in the frequency-domain.

The applicability of the above method to the β Lyrae system discussed. New physical and geometrical elements of these systems are derived. Their positions in the H-R diagram and mass-luminosity diagram are indicated.
