Serial title, monograph or event: | Brazilian Journal of Physics | Volume: | 34 | Issue: | 3a | Abstract: | We investigate the properties of mixed stars formed by hadronic and quark matter in β-equilibrium described by appropriate equations of state (EOS) in the framework of relativistic mean-field theory. We use the non-linear Walecka model for the hadron matter and the MIT Bag and the Nambu-Jona-Lasinio models for the quark matter. The calculations were performed for T = 0 and for finite temperatures in order to describe neutron and proto-neutron stars. The star properties are discussed. Both the Bag model and the NJL model predict a mixed phase in the interior of the star. | URI: | https://hdl.handle.net/10316/110954 | ISSN: | 0103-9733 | DOI: | 10.1590/S0103-97332004000500005 | Rights: | openAccess |
