中子星中高密度物质的性质

Properties of High-Density Matter in Neutron Stars

Fridolin Weber, Gustavo A. Contrera, Milva G. Orsaria, William Spinella, Omair Zubairi

摘要:

这篇简短的评论旨在简要概述被认为存在于中子星超致密中心的各种物质状态。特别强调夸克解除禁闭在中子星中的作用,以及可能存在由绝对稳定的奇异夸克物质组成的致密星(奇异星)。讨论了区分中子星和夸克星的天体物理现象,并探讨了在中子星中是否会发生夸克解除禁闭的问题。结合观测到的天体物理数据,这些研究对于描绘压缩重子物质的复杂结构以及对这种物质的基本未知状态方程施加严格的约束是非常宝贵的。

英文摘要:

This short review aims at giving a brief overview of the various states of matter that have been suggested to exist in the ultra-dense centers of neutron stars. Particular emphasis is put on the role of quark deconfinement in neutron stars and on the possible existence of compact stars made of absolutely stable strange quark matter (strange stars). Astrophysical phenomena, which distinguish neutron stars from quark stars, are discussed and the question of whether or not quark deconfinement may occur in neutron stars is investigated. Combined with observed astrophysical data, such studies are invaluable to delineate the complex structure of compressed baryonic matter and to put firm constraints on the largely unknown equation of state of such matter.
