Finite source depolarization factors for circumstellar scatteringA single scattering theory is used to directly derive the D(r) result of Cassinelli et al (1987) and to investigate the extent to which it can be generalized to nonuniform spherical light sources, nonspherical light sources, arbitrary spatial distributions of scattering electrons, and scattering particles other than electrons. Expressions are also obtained for the factor by which the total scattered (as well as polarized) intensity is modified by finite size light sources, which is relevant to the case where the much stronger direct unpolarized starlight is eclipsed.
