The Eddington factor for radiative transfer in spherical geometry
Abstract
The present paper shows that, contrary to the statement of Hummer & Rybicki, the half-range method (Wilson & Sen) can handle the outward peaking effect of the radiation field in extensive spherical media. The source function J(r) and the Eddington factor f(r) = [K(r)/J(r)] have been calculated by the half-range method with k(r) = for 0 < r < R, where R = 3 and R = lo. The values for R = 10 are compared with those of Hummer & Rybicki and are found to be in fairly good agreement.
