论文摘要
为了通过描述混合相的插值方法替换麦克斯韦的结构，重新审视了最新的超子拼图解决方案。为此，我们首次申请有限范围的多项式插值方法，用于在文献中构建Hadroonic和Quark Wiss阶段之间的过渡到文献中被描述为重新启动问题的情况。为了描述hadronic阶段，最低阶的约束变异方法用于夸克阶段，用于恒定（模型nlnjla）的非局部nambu-jona-lasinio模型，并且使用密度依赖性（模型nlnjlb）参数。将替代插值方法应用于两个夸克物质模型，都会产生一个混合状态方程，该方程允许在纯Hadroonic和Quark相之间的混合相之间存在核物质，超核物质和夸克物质，这也可以在相应的混合恒星序列的结构中实现。预测的杂种恒星满足了从最近观察结果获得的中子星的质量 - 拉迪乌斯关系的约束。
A recent solution of the hyperon puzzle by a first order phase transition to color superconducting quark matter is revisited in order to replace the Maxwell construction by an interpolation method which describes a mixed phase. To do this, we apply for the first time the finite-range polynomial interpolation method for constructing a transition between hadronic and quark matter phases to the situation that is characterized in the literature as the reconfinement problem. For the description of the hadronic phase the lowest order constrained variational method is used while for the quark phase the nonlocal Nambu-Jona-Lasinio model with constant (model nlNJLA) and with density-dependent (model nlNJLB) parameters is employed. Applying the replacement interpolation method to both quark matter models results in a hybrid equation of state that allows a coexistence of nuclear matter, hypernuclear matter and quark matter in a mixed phase between the pure hadronic and quark phases which can also be realized in the structure of the corresponding hybrid star sequences. The predicted hybrid stars fulfill the constraints on the mass-radius relation for neutron stars obtained from recent observations.
