超新星和致密星的状态方程

Equations of state for supernovae and compact stars

M. Oertel, M. Hempel, T. Klähn, S. Typel

摘要:

我们回顾了致密物质状态方程的各种理论方法,这些方法与核心坍缩超新星、致密星和致密星合并的描述有关。重点放在适用于所有这些情况的模型上。这样的EoS模型必须涵盖重子数密度、温度和同位旋不对称性的大范围。在这些范围内,物质的特性发生了巨大的变化,从核子,原子核和电子的混合物到均匀的,强烈相互作用的物质,包含核子,以及可能的其他粒子,如超子或夸克。由于EoS的发展需要来自多个方向的共同努力,我们考虑不同的理论方法,并讨论相关的实验和观测约束,为未来的研究提供见解。最后,从所讨论的EoS模型的应用结果进行了总结。

英文摘要:

We review various theoretical approaches for the equation of state (EoS) of dense matter, relevant for the description of core-collapse supernovae, compact stars and compact star mergers. The emphasis is put on models that are applicable to all of these scenarios. Such EoS models have to cover large ranges in baryon number density, temperature and isospin asymmetry. The characteristics of matter change dramatically within these ranges, from a mixture of nucleons, nuclei, and electrons to uniform, strongly interacting matter containing nucleons, and possibly other particles such as hyperons or quarks. As the development of an EoS requires joint efforts from many directions we consider different theoretical approaches and discuss relevant experimental and observational constraints which provide insights for future research. Finally, results from applications of the discussed EoS models are summarized.
