# Rotation-driven phase transitions in the cores of pulsars

## TL;DR

This paper investigates how the rotation of pulsars influences their internal composition, especially the formation of quark matter during spin-down, using modern nuclear models constrained by observational data.

## Contribution

It introduces a detailed analysis of rotation-driven phase transitions in neutron star cores based on updated nuclear equations of state.

## Key findings

- Rotation can induce phase transitions to quark matter in pulsar cores.
- The study constrains models using recent neutron star mass and radius data.
- Rotation affects the internal composition and structure of neutron stars.

## Abstract

In this paper, we discuss the impact of rotation on the particle composition of rotating neutron stars (pulsars). Particular emphasis is put on the formation of quark matter during stellar spin-down, driven by continuous gravitational compression. Our study is based on modern models for the nuclear equation of state whose parameters are tightly constrained by nuclear data, neutron star masses, and the latest estimates of neutron star radii.
