Binary Hybrid Star Mergers and the Phase Diagram of Quantum Chromodynamics — •Matthias Hanauske1,2, Luciano Rezzolla1,2, and Horst Stöcker1,2,3 — 1Institute for Theoretical Physics, Goethe University Frankfurt, Germany — 2Frankfurt Institute for Advanced Studies, Frankfurt am Main, Germany — 3GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany
The astrophysical consequences of a hadron-quark phase transition (HQPT) in the interior of a neutron star merger product will be focused within this presentation. The results of numerical simulations of binary neutron star mergers will be presented, where a strong HQPT has been implemented in the equation of state of the underlying elementary matter of the compact star binary. The evolution of the density and temperature distributions inside the produced hypermassive hybrid star will be analysed and visualised in a QCD phase diagram manner. The results show that the appearance of the HQPT in the interior region of the produced hypermassive hybrid star will change the spectral properties of the emitted gravitational wave, if the phase transition is strong enough.
