Impact of Rotation on Quark-Hadron Hybrid Stars

TL;DR

This paper investigates how rotation affects quark-hadron hybrid stars and compares theoretical models with recent observations to identify which EOSs are consistent with observed rapidly rotating neutron stars.

Contribution

The study analyzes the impact of rotation on hybrid stars and evaluates the consistency of different EOS models with recent observational data.

Findings

One EOS aligns with recent observations of rotating neutron stars.

Another EOS is inconsistent with observational data.

Rotation significantly influences the properties of hybrid stars.

Abstract

Many recent observations give restrictions to the equation of state (EOS) for high-density matter. Theoretical studies are needed to try to elucidate these EOSs at high density and/or temperature. With the many known rapidly rotating neutron stars, e.g., pulsars, several theoretical studies have tried to take into account the effects of rotation. In our study of these systems, we find that one of our EOSs is consistent with recent observation, whereas the other is inconsistent.
