论文摘要
我们研究了爱因斯坦重力理论中球形对称各向异性相对论恒星的重力崩溃，利用了我们最近开发的一种崩溃的恒星模型[{\ it Astrophys。 Space Sci。} {\ BF361} 99（2016）]。在常规初始条件下，根据黑洞的形成，分析了大量恒星在常规初始条件下连续重力崩溃的最终状态。为了研究经历重力崩溃的各向异性恒星的演变，假定耗散过程以径向热量升温的形式发生。内部时空由静态度量与vaidya指标匹配，描述了辐射恒星的外部。最初的静态配置由Paul和Deb [{\ it Astrophys获得的相对论解决方案描述。 Space Sci。} {\ BF354} 421（2014）]。研究了各向异性对巨大恒星动力学崩溃的影响。 Maxwell-Cattaneo方程的相对论因果热传输方程用于显示各向异性对崩溃系统温度曲线的依赖性。
We study the gravitational collapse of a spherically symmetric anisotropic relativistic star within Einstein theory of gravity making use of one of our recently developed collapsing stellar models [{\it Astrophys. Space Sci.} {\bf361} 99 (2016)]. The final state of continual gravitational collapse of a massive star under regular initial conditions is analyzed in terms of the formation of black holes. To study the evolution of an anisotropic star undergoing gravitational collapse, it is assumed that the dissipation process happens in the form of radial heat-flux. The interior space-time is described by static metric matched at the boundary with Vaidya metric that describes the exterior to the radiating star. The initial static configuration is described by the relativistic solution obtained by Paul and Deb [{\it Astrophys. Space Sci.} {\bf354} 421 (2014)]. The impact of anisotropy on the dynamical gravitational collapse of a massive star is studied. The relativistic causal heat transport equation of the Maxwell-Cattaneo equation is utilized to show the dependence of anisotropy on the temperature profile of the collapsing system.
