Scientific paper

The aim of the present paper has been to analyze the light changes of the close eclipsing system SX Aurigae in the frequency-domain. This analysis is based on Kopal's new theory recently developed for the study of light variations, between minima as well as within eclipses, of close eclipsing binaries whose components are distorted by axial rotation and mutual tidal action. A method for the separation of the photometric proximity and eclipse effects directly from the observed data is also presented. In this method no 'rectification' is needed. The automated method has been tested on the light curves of SX Aurigae. Finally, a comparative discussion is given of Kopal and Kitamura methods of the light curves analysis.
