An effective geometry treatment of general relativistic radiative transfer inside stellar photospheres

The aim of this paper is to determine how the gravitational field inside a massive star affects the propagation of photons, and to investigate the consequences for the radiation field. The chosen approach consists in modeling the curved metric by an effective refractive medium: from this very simple perspective, the energy transport problem is investigated and the new form of the radiative transfer is derived. Then, the main effects of curvature on the energy balance are discussed and, in particular, it is shown that these effects influence the radiative flux emitted by the star.
