Stochastic forces on electrons in the solar flare plasma

Abstract

A Langevin equation for electrons in the plasma of a solar flare with electrostatic lower-hybrid-drift turbulence is developed from first principles and in consistency with the kinetic theory in the polarization approximation. The waves are assumed to be excited by small density gradients causing drift velocities below the thermal ion velocity. First utilizable expressions for the space-time spectral density of the wave energy are given, and estimates of the mean wave force on an electron as well as of the intensity of the stochastic wave force are made. It seems that almost electrostatic lower-hybrid-drift waves could contribute to electron chaotization in solar flare plasmas.
