Analysis of the light curves of V78 in ω Centauri in the frequency domain by automatized fourier techniques

  • A. I. Kaskambas


The aim of the present paper has been to analyse the light changes of the close eclipsing system V78 in ω Centauri in the frequency domain. In two of his recent papers, Kopal (1977b, c) has developed new methods for the analysis of light curves using Hankel transforms of zero order. He succeeded in expressing the momentsA2m of light curves in a closed form. The expansions, in terms of which the momentsA2m can be expressed, converge in all circumstances. Their analytical structure presents no difficulty for automatic computation. The light variations of the eclipsing system V78 in ω Centauri have been studied by use of the above method. New geometrical elements are also given.
