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 in the study of the thermodynamic properties of such systems and relate it to recent nonequilibrium thermodynamic theories. Finally we comment the possibility of introducing a nonequilibrium chemical potential for photons.", "revisions": [ { "version": "v1", "updated": "1997-09-09T13:42:01.000Z" } ], "analyses": { "keywords": [ "information theory", "non equilibrium anisotropic radiation", "two-parameter eddington factor", "variable eddington factor scheme", "nonequilibrium thermodynamic theories" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
