Abstract

The aim of the present paper has been to analyse the light changes of the close eclipsing system AK Herculis 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 new 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. New elements taking into account the photometric perturbations are also given.
