Magnetohydrodynamics Stability of A Compressible Fluid Layer below A Vacuum Medium

Abstract

The instability analysis of a compressible fluid layer acted by capillary, pressure gradient, external gravity and electromagnetic forces has been developed on the basis of the linear perturbation technique . A general relation is derived and discussed analytically and numerically for all values of amplitude disturbances. This model has many applications in Astronomy as the interface of an expanding supernova remnant and in Geology during the geological drillings in the crust of the earth.
