Why {\em Explicit} Strangeness Is Not Relevant In Compact Stars

TL;DR

This paper argues that explicit strangeness is not relevant in compact stars, using skyrmion models and Wilsonian renormalization to show quark strangeness can be replaced by hadronic degrees of freedom.

Contribution

It introduces a topological approach to replace quark strangeness with hadron degrees of freedom in dense matter models of compact stars.

Findings

Strangeness does not explicitly influence compact-star matter.

Skyrmion models effectively describe dense matter without explicit strangeness.

Topological methods can replace quark degrees of freedom in dense matter modeling.

Abstract

Drawing largely from my work with co--workers, I present arguments that strangeness does not play an {\it explicit} role in compact-star matter. They are based on the skyrmion description of dense matter combined with Wilsoninan renormalization group approach to kaon nuclear interactions. The key idea is that quark degrees of freedom, carrying strangeness, can be traded in by topology for hadron degrees of freedom.
