Spherically symmetric gravitational collapse in the background of Chaplygin gas

Abstract

This paper considers the spherically symmetric gravitational collapse in the background of Chaplygin gas as dark energy component. The dark energy is assumed to be generalized and modified Chaplygin gas. The exterior of the star is considered to be Schwarzschild de-sitter/anti-de sitter metric and discusses the junction conditions. We have discussed the singularity formation in both forms of chaplygin gas case and it is obtained that such collapsing fluids favor the formation of black-hole.
