摘要:

随着核物质多体理论的发展,在不久的将来,通过理论计算与核性质、核反应的实验室测量以及天文学中越来越精确的观测的对抗,人们可能会理解致密物质状态方程这个长期存在的、悬而未决的问题。本文主要从以下六个方面进行了综述:1)综述了夸克平均场(QMF)模型,该模型从夸克势出发描述了核子和多体核子系统,2)将QMF应用于核物质和中子星,3)将QMF模型扩展到描述超核、超子物质和超子星,4)将QMF模型应用于描述中子星和中子星。4)将QMF模型与以声速表征的夸克物质模型相结合,探索强子-夸克相变和混合星:5)利用双星并合事件GW 170817的引力波信号和电磁波信号约束夸克间的相互作用; 6)讨论从致密天体研究致密物质物态方程的进一步机会,如中子星冷却和脉冲星故障。

英文摘要:

Because of the development of many-body theories of nuclear matter, the long-standing, open problem of the equation of state (EOS) of dense matter may be understood in the near future through the confrontation of theoretical calculations with laboratory measurements of nuclear properties \& reactions and increasingly accurate observations in astronomy. In this review, we focus on the following six aspects: 1) providing a survey of the quark mean-field (QMF) model, which consistently describes a nucleon and many-body nucleonic system from a quark potential; 2) applying QMF to both nuclear matter and neutron stars; 3) extending QMF formalism to the description of hypernuclei and hyperon matter, as well as hyperon stars; 4) exploring the hadron-quark phase transition and hybrid stars by combining the QMF model with the quark matter model characterized by the sound speed; 5) constraining interquark interactions through both the gravitational wave signals and electromagnetic signals of binary merger event GW170817; and 6) discussing further opportunities to study dense matter EOS from compact objects, such as neutron star cooling and pulsar glitches.
