摘要
We present a new model of dissipative energy fluid without appearance of horizon. The interior matter fluid is shear-free isotropic spherically symmetric and undergoing radial heat flow. The interior metric is matched with Vaidya exterior metric over the boundary. The model obeyed all the relevant physical and thermodynamic conditions. In this model, the collapse begins at infinite past with both infinite mass and radius and contracts to a point as time tends to zero without forming an event horizon.
