Description
We discuss the nature of phase transitions in the self-gravitating Fermi gas in Newtonian gravity and general relativity. When the particle number is above the Oppenheimer-Volkoff limit, we evidence the existence of a new turning point of mass-energy in the caloric curve leading to the collapse of the system towards a black hole. We mention possible applications of these results to the case of fermionic dark matter halos with a core-halo structure made of a fermion ball surrounded by an isothermal atmosphere.
