Application of the integral method to plotting of the light curve and for determining the mean radius of XZ Cyg.
Abstract
The light curves of XZ Cyg are calculated for two phases of the Blazhko effect (at minimum and maximum light-variation amplitudes) from variations of radius and temperature, with allowance for the content of heavy elements in the stellar atmosphere. Mean radii of 3.83 x 10 to the 11th cm and 3.90 x 10 to the 11th cm were obtained for minimum and maximum light-variation amplitudes, respectively, on the basis of a comparison of calculated and observed light curves.
