标题： Relativistic compact object in Generalised Tolman-Kuchowicz spacetime with quadratic equation of state

摘要： 本文利用广义托尔曼-库霍维奇时空度规和二次状态方程，给出了未荷电静态球对称致密天体PSR J0952-0607的爱因斯坦场方程解类。 我们通过图形方法得到了模型参数n的界限，并获得了致密天体数学模型的稳定恒星结构。 生成模型的稳定性通过托尔曼-奥本海默-沃尔科夫方程以及哈里森-泽尔多维奇-诺维科夫准则进行了检验。 该各向异性致密星模型满足所有必要的稳定性标准，包括因果性条件、绝热指数和布赫达尔条件，且不存在中心奇点。 显示英文摘要

摘要： This paper presents the class of solutions to the Einstein field equations for the uncharged static spherically symmetric compact object PSR J0952-0607 by using Generalized Tolman-Kuchowicz space-time metric with quadratic equation of state. We have obtained the bound on the model parameter n graphically and achieved the stable stellar structure of the mathematical model of a compact object. The stability of the generated model is examined by the Tolman-Oppenheimer-Volkoff equation and the Harrison-Zeldovich-Novikov criterion. This anisotropic compact star model fulfills all the required stability criteria including the causality condition, adiabatic index, and Buchdahl condition, Herrera's cracking condition and pertains free from central singularities.
