- Description
- Over the late years a growing discussion has taken on on whether or not there exists a solution of Einstein's equations which describes the formation of eternally-collapsing astrophysical compact objects other than black holes. Here we address the issue using a general relativistic perturbation theory assessment where dissipation through heat flow produces a null radiation. It is shown that a purely gravitational eternally-collapsing compact object (GECO) can indeed be formed only during the collapse of a supermassive star, whose radius after collapse is larger than the Schwarzschild's. The self-consistently computed opacity of the material composing the supermassive star, which radiates at the Eddington luminosity limit, is in agreement with stellar evolution and nuclear physics standards. Yet the perturbed mass responsible for the GECO luminosity is determined by the heat flux and the work done by the gas pressure restraining the collapse.
