Determination of the Elements of Eclipsing Variables RW Tauri and U Sagittae by an Analysis of the Light Changes in the Frequency Domain
Abstract
The aim of the present paper has been to present an analysis of the light changes of two eclipsing systems RW Tau and U Sge in the frequency domain, which was developed by Kopal (1975a, b, c, d, e, 1976). Following a brief introduction, Section 2 contains the evaluation of the theoretical momentsA 2m. The determination of the preliminary elements and their improvement, taking into account the photometric perturbations, are given in Sections 3 and 4. A general discussion devoted to the whole analysis of the system is presented in Section 5.
