Description

The core of a neutron star is an entity of enigma due to the mystery surrounding its composition. Insights from nuclear theory and perturbative QCD suggest the possible existence of hybrid stars having a phase transition from hadronic matter to quark matter. This study presents how different types of phase transition (namely, Maxwell and Gibbs) can leave imprints on gravitational waves from binary neutron star mergers and how this helps us to differentiate types of phase transition from post-merger signals. We also comment on the type of phase transition for the merger event of GW170817.
