Hadron-quark phase transition in neutron stars

摘要：

We study the hadron-quark phase transition in the interior of neutron stars.The relativistic mean field (RMF) theory is adopted to describe the hadronic matter phase,while the Nambu-Jona-Lasinio (NJL) model is used for the quark matter phase.We investigate the influence of the hadronic equation of state on the phase transition and neutron star properties.It is found that a neutron star possesses a large population of hyperons,but it is not dense enough to possess a pure quark core.Whether or not the mixed phase of hadronic and quark matter appears in the center of neutron stars depends on the RMF parameters used in the calculation.
