Cylindrical shock in a self-gravitating gas
Abstract
The propagation of a diverging cylindrical shock in a self-gravitating gas has been studied for the two cases: (1) when the shock is strong and (2) when it is weak. Analytical relations for shock velocity and shock strength have been obtained. It is shown that for a strong shock, the shock velocity must decrease continuously with shock propagation; for a weak shock, it initially decreases and attains a minimum value over a certain propagation distance, after which it starts increasing. Finally, expressions for the pressure, the density, and the particle velocity immediately behind the shock have been obtained for both the cases.
