【摘要】 利用微扰方法研究旋转混合星的结构.应用基于相对论平均场理论的硬和软的两种强子物质状态方程以及将s夸克质量作为自由参量的夸克物质的MIT袋模型来构造混合星模型.研究了旋转对于星体内部结构的影响,并近一步对比和分析不同模型星体结构改变的不同.结果显示s夸克质量对于旋转星体的结构和性质有较大的影响.更多还原

【Abstract】 The stiff and soft hadronic matter equations of state in the framework of the relativistic mean-field (RMF) theory and MIT bag model of quark matter with free parameter-s quark mass are used to construct the model of hybrid stars. The change of the internal structure of the star due to rotation has been investigated, and the effect of different model bringing to configuration of star has been analyzed. The s quark mass is a prominent factor which influences deformation properties of rotating hybrid stars.更多还原
