Sažetak
The Thomas-Fermi model at finite temperature is extended
to describe a system of self-gravitating weakly interacting
massive fermions in a general-relativistic framework.
The existence and properties of the gravitational phase transition
in this model are investigated numerically. It is shown that,
by cooling a nondegenerate gas of weakly interacting massive
fermions below some critical temperature, a condensed phase emerges,
consisting of quasidegenerate fermion stars. For fermion masses
of 10 to 25 keV, these fermion stars may very well provide
an alternative explanation for the supermassive compact dark
objects that are observed at galactic centers.
