# Estrellas h\'ibridas: una aproximaci\'on semi-anal\'itica a T finita

## TL;DR

This paper develops a semi-analytic model for the equation of state of proto-hybrid stars with quark matter cores, analyzing their mass-radius relations and comparing with observed neutron star data.

## Contribution

It introduces a semi-analytic approach to model the EoS for proto-hybrid stars including nuclear and quark matter at finite temperature.

## Key findings

- Mass-radius relationships consistent with observed pulsars.
- Proto-hybrid stars can match observed neutron star masses.
- The model constrains the properties of quark matter in stellar cores.

## Abstract

Starting from the semi-analytic construction of a equation of state (EoS) which takes into account nuclear and quark matter at finite temperature, we study the possibility that proto-neutron stars, be proto-hybrid stars whose cores are composed of quark matter. We obtain the mass-radius relationship and discuss the latest constraints on masses and radii of neutron stars, considering the pulsars PSR J1614-2230 and PSR J0348 + 0432.
