Thermosolutal Instability of a Hall Plasma

Abstract

The thermosolutal convection in a layer of viscous plasma heated from below and subjected toa stable solute gradient is investigated in the presence of Hall currents. For the case of stationary convection, the stable solute gradient and the Hall currents are found to have stabilizing and destabilizing effects respectively on the system. The question of the onset of instability as overstability is also discussed
