| 英文摘要 | In this paper, we use the equation of state based on a modification of the 2+1 flavors Nambu-Jona-Lasinio (NJL) model to study the quark matter of hybrid stars. For comparison, we utilize five EOSs of the relativistic mean-field (RMF) model to describe the hadronic phase. With the three-window crossover interpolation approach, we try to construct relatively soft hybrid EOSs but find the maximum masses of hybrid stars do not differ much. The results are quite close to the 2 solar mass, which is consistent with the mass constraint of PSR J0348 + 0432. Furthermore, it is noteworthy that the heaviest stable stars have central densities higher than that of the deconfinement transition, suggesting a pure quark core in the hybrid star. |
