Mirror and Firehose Instabilities in the Heliosheath

  title={Mirror and Firehose Instabilities in the Heliosheath},
  author={Vincent G{\'e}not},
We investigate the nature of the heliosheath plasma behind the termination shock across which jump relations in anisotropic MHD are formulated. Along side analytical results for downstream parameters in the strictly parallel and perpendicular cases we numerically solve the Rankine-Hugoniot relations for arbitrary shock angle and strength. We then focus on two temperature anisotropy driven instabilities which have attracted attention in many other astrophysical situations, namely the mirror and… CONTINUE READING
