论文摘要
我们研究了完全相对论中轴对称旋转中子星的热演化。为此，我们开发了“ NScool 2D Rot”，这是D. Page对1D中子星热演化代码“ NScool”的主要升级。作为我们新代码的第一个应用，我们解决了旋转频率至质量脱落极限的孤立中子星的标准冷却。我们通过考虑核心和地壳EOSS的不同组合来研究状态方程（EOS）的影响。结果表明，在整个恒星的整个体积，尤其是在地壳中，温度分布的复杂时间相关的演变。我们表明，大多数复杂性可以归因于地壳中的“热斑点”的形成，归因于通过地壳的热扩散时间尺度的纬度依赖性。
We study the thermal evolution of axisymmetric rotating neutron stars in full general relativity. To this aim we develop "NSCool 2D Rot", a major upgrade of the 1D neutron stars thermal evolution code "NSCool" by D. Page. As a first application of our new code we address the standard cooling of isolated neutron stars with rotation frequencies up to the mass shedding limit. We investigate the effects of the equation of state (EOS) by considering different combinations of core and crust EOSs. The results indicate complex time-dependent evolution of temperature distribution throughout the whole volume of the star and, in particular, in the crust. We show that most of that complexity can be attributed to the formation of a "heat blob" in the crust and to the latitude dependence of the heat diffusion timescale through the crust.
