Abstract EN
The nonlinear phenomena which associate with magnetoacoustic waves in a plasma are analytically studied.
A plasma is an open system with external inflow of energy and radiation losses.
A plasma’s flow may be isentropically stable or unstable.
The nonlinear phenomena occur differently in dependence on stability or instability of a plasma’s flow.
The nonlinear instantaneous equation which describes dynamics of nonwave entropy mode in the field of intense magnetoacoustic perturbations is the result of special projecting of the conservation equations in the differential form.
It is analyzed in some physically meaningful cases; those are periodic magnetoacoustic perturbations and particular cases of heating-cooling function.
A plasma is situated in the straight magnetic field with constant equilibrium magnetic strength which form constant angle with the direction of wave propagation.
A plasma is initially uniform and equilibrium.
The conclusions concern nonlinear effects of fast and slow magnetoacoustic perturbations and may be useful in direct and inverse problems.
