Scientific paper

The photospheres of hot stars (or other astrophysical objects) in which scattering of the radiation by free electrons is important are considered. The ratio of the coefficient of electron scattering to the absorption coefficient is assumed to be an arbitrary function of the optical depth. A linear integral equation is obtained that directly determines the intensity of the radiation leaving the star. This equation is solved numerically for the case of an isothermal photosphere in which the density varies in accordance with the barometric law. In this case, an asymptotic expression is also given for the radiation intensity.
