Research of influence of plasma inhomogeneity on Alfvén wave nonlinear absorption by dissipative plasma when considering photorecombination radiation

M. B. Gavrikov, A. A. Tayurskii
References:
Abstract: The nonlinear absorption of Alfvén wave in an inhomogeneous incompressible dissipative plasma is investigated. It is shown that accounting for bremsstrahlung and photorecombination radiation leads to the finiteness of the penetration depth of the Alfvén wave into a dissipative plasma and to the appearance of a steady quasistationary absorption regime. Accounting for synchrotron radiation has practically no effect. Density distributed over a Gaussian law of two types-the hump and hollows-are considered. Dependences of the depth of penetration of the Alfvén wave and the maximum values of the temperatures of electrons and ions on the value of the hump are obtained.
Keywords: classical MHD, electromagnetic hydrodynamics (EMHD), Alfvén wave, bremsstrahlung, photorecombination radiation, synchrotron radiation.
