Spherical variableenergy blast wave in selfgravitating gas.
Abstract
Modified similarity method has been used to study the propagation of sphericalvariable energy blast waves through a selfgravitating gas. For an energy inputE _{α}=E _{0}t^{4/3}, whereE _{α} is the energy released up to timet andE _{0} is a functional constant, the similarity solutions correct up to third approximation have been obtained. It is found that the effects of selfgravitational forces are of third order. An increase in the parameterA ^{2} (characterising the gravitational field) increases the shock velocity.
