Self-inhibiting heat flux

Abstract
Heat transfer through weakly magnetized diffuse astrophysical plasmas excites whistlers. This leads to electron whistler resonant scattering, a reduction of the electron mean free path, and heat flux inhibition. However, only whistlers propagating at a finite angle to the magnetic field (off-axis) can scatter the heat flux carrying electrons. Thus the level of heat flux inhibition along the magnetic field lines depends on the presence of off-axis whistlers.  We obtain a solution of the Boltzmann equation with the whistler wave equation and show that if ethβe ≫ 10−4, where eth is the thermal collisional Knudsen number and βe is the ratio of the electron pressure ...
