# Strangeon Stars

## TL;DR

This paper introduces the concept of strangeon stars, a new type of compact stellar object composed of strangeons, which are 3-flavored baryonic matter, and discusses their formation, properties, and potential observational signatures.

## Contribution

It proposes strangeon stars as a novel stable baryonic matter state, explaining their formation and how they can be distinguished from other compact stars.

## Key findings

- Strangeon matter could form stable compact stars.
- Strangeon stars may form if quark deconfinement is suppressed.
- Identification of strangeon stars requires further micro-model development.

## Abstract

Stable micro-nucleus is 2-flavored (u and d), whereas stable macro-nucleus could be 3-flavored (u, d and s) if the light flavor symmetry restores there. Nucleons are the constituent of a nucleus, while strangeons are named as the constituent of 3-flavored baryonic matter. Gravity-compressed baryonic object created after core-collapse supernova could be strangeon star if the energy scale (~0.5 GeV) cannot be high enough for quark deconfinement and if there occurs 3-flavor symmetry restoration. Strangeon stars are explained here, including their formation and manifestation/identification. Much work, coupled with effective {micro-model} of strangeon matter, is needed to take advantage of the unique opportunities advanced facilities will provide.
