Modified MIT Bag Models—part II: QCD phase diagram and hot quark stars

Abstract In the present work we use modified versions of MIT bag model, on which both a vector field and self-interacting term are introduced, to obtain hot quark matter investigate QCD phase diagram. We first analyze two-flavored constrained freeze-out liquid-gas transition at hadronic phase. Later, three-flavored subject β equilibrium charge neutrality is used compute star macroscopic properties, confronted with recent observational massive canonical radius results. Finally, comparison diagrams obtained from Nambu-Jona-Lasinio model performed.
