Polarized radiative transfer equation in some nontrivial coordinate systems
J.Freimanis

Abstract

AGB stars, post-AGB objects, protoplanetary nebulae and young planetary nebulae often have gas-dust shells of complex morphology and nontrivial geometry. Conical, toroidal, maybe ellipsoidal and other structures are often observed. Radiation coming from these objects is usually highly polarized.

While modeling such objects it is desirable to solve the corresponding equations of mathematical physics in such a coordinate system which reflects the symmetry of the astronomical object. A general method to derive polarized radiative transfer equation in different coordinate systems was developed recently (Freimanis 2011). In this contribution, the general method is applied to several coordinate systems of type mentioned above, and clear expressions for polarized RTE are obtained.
