Query: Stability windows at finite temperature   The assumption underlying the existence of quark stars is based on the
Bodmer-Witten conjecture. These authors have claimed that it is possible that
the interior of a neutron-like star does not consist primarily of hadrons, but
rather of the strange matter (SM). Strange matter is composed of deconfined
quarks, including up, down and strange quarks, plus the leptons necessary to
ensure charge neutrality and \beta-equilibrium. This possibility arises because
a phase transition from hadronic to quark phase is possible at densities
present in the interior of neutron stars. It has been argued that strange
matter is the true ground state of all matter. If this is the case, as soon as
the core of the star converts to the quark phase, the entire star converts. SM
was first considered in calculations obtained within the MIT bag model
framework. More sophisticated treatments for SM, based on the quark-mass
density dependent model is considered in this work. We discuss next the
following models for proto-quark stars: the QMDD model, and the MIT bag model.
