Sv. Molodtsov, A GENERALIZATION OF KOMPANEETS EQUATION FOR ANISOTROPIC PHOTON DISTRIBUTION IN SLOWLY MOVING GAS WITH ARBITRARY DEGENERACY, Astronomy letters, 20(2), 1994, pp. 256-262
A generalization of Kompaneets's equation is given for the photon dist
ribution function in the energy exchange between photons and electrons
due to the Compton effect. The anisotropic function of the photon dis
tribution in the slowly moving high-temperature gas with arbitrary deg
eneracy is assumed. Most of the factors of the kinetic equation are ch
aracterized by the simple dependence on the degree of degeneracy and a
re proportional to the number density of particles.
