The intrinsic light variation in very close eclipsing binary systems with distorted components
Abstract
Using the theory of distorted components in very close binaries the semiaxes are computed for several possible models. The coefficients of limbdarkening and gravity effect are found as weighted mean values of the results of several theoretical investigations. A simple linear relation is found between the coefficient of limbdarkening and the logarithm of the effective temperature in the spectral interval A0 to K0. The Fourier series for the intrinsic light variation of such distorted components is given for any polytropic index. The influence of the tidal bulge is described in detail.
