Self-inhibiting heat flux: A chance for snowballs in hell? Academic Article uri icon


  • We obtain a solution of the Boltzmann equation with the whistler wave equation and show that if e th β e ⪢10 −4 , where e th is the thermal Knudsen number, and β e is the ratio of the electron pressure to the magnetic energy density, scattering of heat flux carrying electrons by off-axis whistlers, which are shown to propagate at about 65°, is efficient enough to lead to heat flux inhibition along field lines. The inhibition so obtained is proportional to ( e th β e ) −1 .
