Strong Spherical Shock in Azimuthal Magneti Field Self-Gravitating Gas

Abstract

Propagation of shock waves depends on the medium, its’ viscosity, conductivity, rotation, radiative heat effect and magnetic field too. The aims of present paper is to study the propagation of strong spherical shock waves in a self-gravitating gas atmosphere in presence of magnetic field. Since the azimuthal component of the magnetic field is more effective in comparison to other components, therefore only azimuthal component of the magnetic field is considered here. The problem is explored for two cases (i) when shock moves freely and (ii) when it moves under the influence of overtaking disturbance. Assuming exponential density distribution, the analytical relations for shock velocity and shock strength have been obtained for both the cases. It is found that magnetic field affects the Shock strength very effectively.
