Abstract
A new method has been developed by Kopal (1977c, Paper XII) to make use of expressions for the fractional loss of light α0l of the arbitrarily limb-darkened stars in the form of Hankel transforms of zero-order, in order to evaluate the explicit forms of the α0l ′s for different types of eclipse, as well as of the momentsA2m of the respective light curves in a closed form. The automated method has been tested successfully on the light curves of RT Persei. Also, a photometric curve fit of RT Persei is investigated by application of numerical quadratures to determine the theoretical light curve appropriate for the Roche model. Finally a comparative discussion is given of various methods of light curve analaysis.
