Magnetosonic Excitation of the Entropy Perturbations in a Plasma with Thermal Conduction Depending on Temperature

Nonlinear excitation of the entropy perturbations by magnetosonic waves in a uniform and infinite plasma model is considered. The wave vector slow or fast mode forms an arbitrary angle θ (0≤θ≤π) with equilibrium straight magnetic field, all are functions time longitudinal coordinate. Thermal conduction only factor which destroys isentropicity causes nonlinear mode. A dynamic equation derived describes perturbation field dominant Effects associatiated temperature dependent anisotropic thermal considered discussed.
