摘要：

In this paper, shear-free gravitational collapse with heat flux is discussed by considering higher dimensional spherically symmetric space-time as interior metric and higher dimensional Vaidya space-time as exterior metric. The effects of dissipation on collapse are investigated. A simple approximate higher dimensional conformally flat model is proposed that satisfies the junction conditions. Temperature profile of the proposed model is also calculated. It is concluded that dissipation decreases the collapsing rate and temperature profile of the suggested model.
