论文摘要
在本文中，我们研究了由Hadron（中子，质子，Sigmas，Lambdas），Leptons（电子，Muons）和夸克（上，向上，向下，奇怪）组成的杂种恒星的结构。我们使用相对论的平均场（RMF）模型，即HADRONIC相和MIT袋模型的Sigma-Omega-Rho模型以及夸克相的NJL模型。此外，还采用了麦克斯韦和吉布斯条件来研究强子夸克相变。最后，通过获得Mass-Radius关系，可以预测$ M（m_ {sun}）\ leqslant 2.07 $。
In this paper, we investigate the structure of hybrid stars consisting of hadrons (neutrons, protons, sigmas, lambdas), leptons (electrons, muons), and quarks (up, down, strange). We use a relativistic mean-field (RMF) model namely the Sigma-omega-rho model for the hadronic phase and the MIT bag model as well as the NJL model for the quark phase. In addition, Maxwell and Gibbs conditions are employed to investigate the hadron-Quark phase transition. Finally, by obtaining the mass-radius relation, $ M (M_{sun}) \leqslant 2.07 $ is predicted for such hybrid stars.
