摘要：

中子星诞生于核心坍缩超新星的余波中，它所包含的物质在特殊的密度和温度条件下很难在实验室中重现。近年来，中子星的观测已经开始产生新的见解，强相互作用的物质在高密度区，目前的理论模型受到挑战的性质。同时，手征有效场论已经发展成为一个强有力的框架，研究核物质的性质与量化的不确定性在中等密度区的中子星模型。在这篇文章中，我们回顾了手征有效场论的最新发展，并重点介绍了多体微扰理论作为计算热密核物质性质的有效工具。我们还展示了如何有效场论，使统计上有意义的比较核理论预测，核实验和观测约束的核物质状态方程。

英文摘要：

Born in the aftermath of core collapse supernovae, neutron stars contain matter under extraordinary conditions of density and temperature that are difficult to reproduce in the laboratory. In recent years, neutron star observations have begun to yield novel insights into the nature of strongly interacting matter in the high-density regime where current theoretical models are challenged. At the same time, chiral effective field theory has developed into a powerful framework to study nuclear matter properties with quantified uncertainties in the moderate-density regime for modeling neutron stars. In this article, we review recent developments in chiral effective field theory and focus on many-body perturbation theory as a computationally efficient tool for calculating the properties of hot and dense nuclear matter. We also demonstrate how effective field theory enables statistically meaningful comparisons between nuclear theory predictions, nuclear experiments, and observational constraints on the nuclear equation of state.
