论文摘要
在标准模型之外，研究中子星（NSS）的热演化是物理探针。我们首先详细回顾了NSS的标准冷却理论，重点是核子超流体的作用。然后，我们与轴突和暗物质（DM）讨论非标准进化；轴突产生增强了冷却，而DM积聚会导致NSS加热。为了评估DM加热的效果，我们需要将其与旋转化学加热进行比较，这是由NS中的不平衡beta过程引起的。在论文中，我们还研究了在中子和质子超流体存在下的旋转化学加热。
Thermal evolution of neutron stars (NSs) is studied as a probe of physics beyond the standard model. We first review the standard cooling theory of NSs in detail, with an emphasis on the roles of nucleon superfluidity. Then we discuss non-standard evolution with axion and dark matter (DM); axion production enhances the cooling while DM accretion leads to heating of NSs. To evaluate the effect of DM heating, we need to compare it to the rotochemical heating, which is caused by the out-of-equilibrium beta processes in a NS. In the dissertation, we also investigate the rotochemical heating in the presence of both neutron and proton superfluidity.
