Wave Processes in Plasma Astrophysics

Theoretical studies of wave processes in rotating astrophysical plasma are discussed, with a particular emphasis on new theoretical models of astrophysical plasma such as the magnetohydrodynamic shallow water approximation and anelastic approximation, together with the frequently-used Boussinesq approximation. In addition to the traditional approximation for Coriolis force, effects are discussed, which are caused by its non-traditional representation that accounts for the horizontal rotation component. Linear waves in such plasma are described in detail, and their dispersion properties are discussed. An overview of instabilities in astrophysical plasma is given, which are caused by nonlinear effects.
