Abstract

This review discusses the thermal evolution of neutron star crusts, focusing on recent advancements in cooling models, superfluidity, and surface composition. The cooling process primarily occurs through neutrino radiation and thermal conduction, with the surface temperature of young neutron stars remaining stable for about 100 years before the internal temperature gradually decreases. The paper also discusses challenges such as uncertainties in the equation of state and limited observational data. By bridging the gap between theoretical predictions and observational data, this review aims to deepen our understanding of the thermal evolution of neutron stars.

中子星表面热辐射的研究

本文讨论了中子星壳的热演化，重点介绍了中子星壳在冷却模型、超流动性和表面组成方面的最新进展。冷却过程主要通过中微子辐射和热传导进行，年轻中子星的表面温度在100年左右保持稳定，内部温度逐渐下降。本文还讨论了状态方程的不确定性和有限的观测数据等挑战。通过弥合理论预测和观测数据之间的差距，本综述旨在加深我们对中子星热演化的理解。

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
