Abstract

All presently known stellar-dynamical constraints on the size and mass of the supermassive compact dark object at the Galactic center are consistent with a ball of self-gravitating, nearly non-interacting, degenerate fermions with mass between 76 and 491 keV/c 2, for a degeneracy factor g = 2. Similar to the masses of neutron stars and stellar-mass black holes, which are separated by an Oppenheimer-Volkoff (OV) limit between 1.4 to 3 M⨀, the masses of the supermassive fermion balls and black holes are separated by an OV limit of 1.1 x 108 M⨀, for a fermion mass of 76 keV/c 2 and g = 2.
