# Neutron Star Mergers and the Quark Matter Equation of State

## TL;DR

This paper reviews how neutron star mergers can reach densities where quark matter may form, and explores how gravitational wave signals could indicate a transition to quark matter during these events.

## Contribution

It summarizes recent simulation results on neutron star mergers with various equations of state, highlighting potential gravitational wave signatures of quark matter transitions.

## Key findings

- Late-time gravitational waves may reveal quark matter presence.
- Different nuclear equations of state affect merger evolution.
- Crossover transitions to quark matter influence gravitational wave signals.

## Abstract

As neutron stars merge they can approach very high nuclear density. Here, we summarized recent results for the evolution and gravitational wave emission from binary neutron star mergers using a a variety of nuclear equations of state with and without a crossover transition to quark matter. We discuss how the late time gravitational wave emission from binary neutron star mergers may possibly reveal the existence of a crossover transition to quark matter.
