Collisional plasma relaxation in the field of a planar gravitational wave

The general relativistic kinetic theory is applied to calculate corrections to the distribution arising from Coulomb collisions of particles in the field of a planar gravitational wave. These corrections are used in corrections to the energy-momentum tensor and in deriving the collisional-damping decrements for gravitational waves for a Boltzmann plasma and for a plasma with degenerate electrons. The largest contribution to the damping decrement in a Boltzmann plasma comes from the ions colliding with the electrons; the decrement increases as T-1/2. In a plasma with degenerate electrons, the decrement decreases linearly as the temperature falls and tends to zero at zero temperature. © 1983 Plenum Publishing Corporation

Kinetics of isotropic expansion of an optically transparent plasma at the compton stage

An exact solution is obtained to the nonrelativistic Focker-Planck equation for electrons at the Compton stage of expansion. The electrons have a Maxwellian distribution whose temperature differs from the radiation temperature. A qualitative analysis is made of the correction to the equilibrium relativistic distribution, and it is shown that elastic collisions of ultrarelativistic and nonrelativistic particles in isotropic expansion do not result in the non-relativistic-particle spectrum. © 1983 Plenum Publishing Corporation

Kinetics of the isotropic expansion of a uniform electron-photon plasma

An analysis is performed of the main stages in the expansion of an electron-photon plasma with collisional processes taken into account. A relativistic Fokker-Planck equation for the electrons in the Compton stage of the expansion is derived from the general covariant kinetic equation. © 1983 Plenum Publishing Corporation
