Abstract:

A form of Burmanns Theorem is used to obtain an expansion of the radiation intensity at the surface of a star as an expansion explicitly dependent on the black body function, absorption coefficient, density, and the first few derivatives of these functions with respect to depth. Conditions for the convergence of the series are established. The expansion is modified for the case of organized outward motion of the surface layer and the effect of this motion on an absorption line is examined. Conditions for the shift of the line center to lower or higher frequencies due to the effects of the organized motion and the decay of temperature in the surface layer are also examined.
