Radiative Transfer in Spherically Symmetric Systems. The Conservative Grey Case

Abstract

A practical computational method is presented for the solution of radiative transfer problems in spherically symmetric systems. This procedure involves iteration on the ‘Eddington factor’ f = K/J and is designed to handle the outward peaking of the radiation field in extended spherical systems. Extensive numerical results are obtained and discussed for systems in which |$k\rho\,=\,{r}^{-n},\text{o}\lt r\leqslant R,\,\text{for}\,n\,=\,3/2,\,2\,\text{and}\,3$|⁠.
