Abstract

Information theory is used to perform a thermodynamic study of nonequilibrium anisotropic radiation. We limit our analysis to a second-order truncation of the moments, obtaining a distribution function which leads to a natural closure of the hierarchy of radiative transfer equations in the so-called variable Eddington factor scheme. Some Eddington factors appearing in the literature can be recovered as particular cases of our two-parameter Eddington factor. We focus our attention on the study of the thermodynamic properties of such systems and relate it to recent nonequilibrium thermodynamic theories. Finally, we comment on the possibility of introducing a nonequilibrium chemical potential for photons.
