STRANGE MATTER EQUATION OF STATE AND THE COMBUSTION OF NUCLEAR-MATTER INTO STRANGE MATTER IN THE QUARK MASS-DENSITY-DEPENDENT MODEL AT T-GREATER-THAN-0

We study the properties and stability of strange matter in the mass-density-dependent model at T > 0. We find the temperature dependence of the strange matter stability window and the critical temperature above which there is no stable strange matter. It occurs at T-c = 34 MeV. Also, the resulting equation of state in this approach is presented. We also study the combustion of nuclear matter into strange matter. We employ for strange matter the equation of state of this paper and for nuclear matter a set of equations of state (free neutrons, Bethe-Johnson, Lattimer-Ravenhall, and Walecka). It is shown that the results are very similar to the ones found employing the MIT bag model. However, the only equation of state which shows a noticeable dependence with temperature is the Walecka one. Moreover, contrary to the former case, the Walecka equation of state is flammable in the present model. It is found that, also at finite temperatures, the properties of strange quark matter in the quark mass-density-dependent model and in the MIT bag model are very similar.
