Compressed Baryonic Matter of Astrophysics

TL;DR

This paper reviews the state of compressed baryonic matter in astrophysics, focusing on the properties of cold matter at nuclear densities and exploring the conjecture of quark-cluster states in stellar cores.

Contribution

It provides a pedagogical review of cold baryonic matter at nuclear densities and discusses the astrophysical conjecture of quark-cluster states.

Findings

Discussion of cold matter properties at nuclear densities

Introduction of the quark-cluster state hypothesis

Implications for supernova and neutron star physics

Abstract

Baryonic matter in the core of a massive and evolved star is compressed significantly to form a supra-nuclear object, and compressed baryonic matter (CBM) is then produced after supernova. The state of cold matter at a few nuclear density is pedagogically reviewed, with significant attention paid to a possible quark-cluster state conjectured from an astrophysical point of view.
