Gravitational phase transition of self-gravitating systems of fermions in General Relativity
Abstract
The Thomas-Fermi model is extended at finite temperature, to describe the gravitational phase transition occurring in massive fermionic systems in a general-relativistic framework. It is shown that, when a nondegenerate fermionic gas (for N < NOV, where NOV is the Oppenheimer-Volkoff limit) is cooled down below a critical temperature, a condensed phase emerges and the gravitational collapse is prevented by quantum mechanics. If N > NOV, by contrast, the system is destined to collapse towards a Black Hole because no equilibrium states exist.
