# Phase Transitions in Neutron Stars

## TL;DR

This paper reviews phase transitions to quark matter in neutron stars, introduces a new model for proto-neutron stars with neutrino trapping, and explores gravitational wave signals as probes of dense matter properties.

## Contribution

It presents a novel description of phase transitions in proto-neutron stars including neutrino effects and analyzes gravitational wave emissions as observational signatures.

## Key findings

- Neutrino trapping influences phase transition dynamics.
- Gravitational waves from deconfinement could be detectable.
- New modeling approach improves understanding of dense matter.

## Abstract

In this paper we review the most common descriptions for the first order phase transition to deconfined quark matter in the core of neutron stars. We also present a new description of these phase transitions in the core of proto-neutron stars, in which more constraints are enforced so as to include trapped neutrinos. Finally, we calculate the emission of gravitational waves associated with deconfinement phase transitions, discuss the possibility of their detection, and how this would provide information about the equation of state of dense matter.
