Scientific paper

We establish the formalism in the nonsymmetric gravitational theory (NGT) for stellar equilibrium and gravitational collapse. We study the collapse of a pressureless, spherically symmetric dust cloud. By assuming that the interior solution is smoothly matched at the surface of the star to the quasi-static, spherically symmetric vacuum solution, we find that the star does not collapse to a black hole. It is anticipated that the final collapsed object will reach a state of equilibrium, and will emit thermal, gravitational and other forms of radiation, although the radiation may be emitted only in small amounts if the red shift from the surface of the compact object is large. No Hawking radiation is emitted and the information loss problem can be resolved at the classical level.
