Diffusion processes in AP stars and white dwarfs
Abstract
Diffusion processes in a fully ionized, multicomponent plasma are investigated. Kinetic phenomena due both to ions and to electrons are considered. The kinetic coefficients are calculated in the two-polynomial approximation of the Chapman-Enskog method. The influence of the magnetic field on transport phenomena is taken into account. The results obtained are compared in detail with the results of other authors. In conclusion, possible astrophysical applications of the theory (surface layers of Ap stars and white dwarfs) are briefly discussed.
