Thermosolutal stability of a two-component rotating plasma with finite Larmor radius

The thermosolutal linear stability of a composite two-component plasma is studied in the presence of Coriolis forces, finite Larmor radius, taking into account the collisions between neutral and ionized particles. The thermosolutal instability appears due to a material convection (thermosolutal convection) in a two component fluid with different molecular diffusivities which contribute in an opposing sense to the locally vertical density gradient. The analysis shows that in the case of a stationary convection, the finite Larmor radius, stable solute gradients and rotation have stabilizing effects. The results also demonstrate that the mutual collisions between ionized and neutral particles does not affect the stationary convection. (authors)
