For a single-component perfect Fermi gas we used the numerical programs
for the equation of state given by Bauer. For a star of hot non-degenerate
neutron gas we calculated the deviations of the internal structure with regard
to a totally degenerate neutron star. For a multi-component perfect gas with
an exponential-type elementary particle spectrum we present the equation of
state. The highest possible temperature is T_0=2*10^12K, where the total
mass density diverges. For the central region of hyperon stars, in contrast
to other authors, we can prove that the time component of the metric tensor
has no singularity, and that the velocity of sound tends to zero ( instead
of rising above the velocity of light ).
