摘要：
This paper deals with the dynamics of a shearfree charged radiating collapse in the modified Gauss-Bonnet gravity. The field equations for shearfree spherical interior geometry of a charged dissipative star are formulated. To study the dynamical behavior of collapsing matter, we derive the dynamical as well as transport equations. We conclude that the gravitational force in the modified Gauss-Bonnet gravity is much stronger as compared to general relativity, which implies the increase in the rate of the collapse. Finally, we study the effect of the charge on the dynamics of the collapse.
