On thermohaline-convective instability with finite Larmor radius and Hall effects

Abstract

Thermohaline-convective instability of a stellar atmosphere in the presence of a stable solute gradient is considered to include the effect due to Hall currents in the presence of a uniform vertical magnetic field. A criterion for monotonic instability is derived. The problem of thermohaline-convective instability is also considered to include finite Larmor radius effect. The criterion derived for monotonic instability is found to hold good in the presence of finite Larmor radius effect on thermohaline-convective instability.
