We report the first results of the extension of the QMC model for asymmetric
dense matter at finite temperature. The effects of temperature on particle
composition (including the full baryon octet content) of the core of
(proto-)neutron stars, as well as on the equation of state, are studied. We
consider both dense matter in chemical equilibrium and matter in which
neutrinos are trapped. In order to simulate stellar temperature profiles that
increase with density and stellar radius, the entropy per baryon is fixed.
Under these conditions, the model predicts that proto-neutron stars are already
born with hyperons present at about the threshold density for their appearance
in cold neutron stars, reaching about 20% of the baryon content in the center
of the most massive star produced.
