EXTENDED RELATIVISTIC NON-EQUILIBRIUM THERMOSTATICS OF STELLAR STRUCTURES WITH RADIATION PRESSURE

Balakin A.B., Tukbaev Z.Z.

We establish the extended formalism for description of the static spherically symmetric relativistic nonequilibrium stellar systems in the formation of which the radiation pressure plays the key role. The main concept of this extended formalism inherits the ideas, on which the Israel-Stewart causal thermodynamics is based, but now the unit spacelike four-vector, indicated by the term director, is exploited in addition to the unit timelike medium velocity four-vector. An application of the extended formalism is considered; we analyze the profiles of the non-equilibrium pressure and temperature as the functions of guiding parameters introduced phenomenologically.
