The Deconfinement Phase Transition in the Interior of Neutron Stars

TL;DR

This paper investigates the deconfinement phase transition inside neutron stars, focusing on entropy production and heat generation, and their effects on the stars' thermal evolution and observable signatures.

Contribution

It introduces a detailed analysis of entropy and heat effects during deconfinement transition, highlighting their impact on neutron star thermal evolution.

Findings

Entropy production can signal phase transition but has limited impact on thermal evolution.

Deconfinement heat significantly alters the thermal evolution of neutron stars.

The study provides insights into observable signatures of phase transitions in neutron star interiors.

Abstract

The deconfinement phase transition which happens in the interior of neutron stars are investigated. Coupled with the spin evolution of the stars, the effect of entropy production and deconfinement heat generation during the deconfinement phase transition in the mixed phase of the neutron stars are discussed. The entropy production of deconfinement phase transition can be act as a signature of phase transition, but less important and does not significantly change the thermal evolution of neutron stars. The deconfinement heat can change the thermal evolution of neutron star distinctly.
