由于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和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，可以理解致密物质状态方程（EOS）的长期开放问题。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和超子物质以及超子星; 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）利用双星合并事件GW 170817的引力波信号和电磁信号约束夸克间相互作用; 6）讨论从致密天体研究致密物质状态方程的进一步机会，如中子星星冷却和脉冲星故障。
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.
