Abstract

A two-shell moment method with three stream division of the radiation field has been suggested for solving radiative transfer problems in a non-grey extended dust shell surrounding a central star. The results computed are found to be of comparable accuracy with those of Unno and Kondo, obtained by generalized Eddington approximation. A more simplified approximation has been put forward for an optically thin medium.
