I will discuss recent developments in inferring the equation of state of zero-temperature beta-equilibrated QCD matter using only ab-initio theoretical results at low and high densities together with robust observational data. In particular, I will introduce a novel method for interpolating the equation of state that allows one to accurately keep track of the speed of sound of neutron-star...

6. Gravitational-Wave Signatures of the Hadron-Quark Phase Transition in Binary Compact Star MergersDr Dr. Matthias Hanauske (Goethe University Frankfurt, Institute for Theoretical Physics)10.11.2020, 11:30QCD phase diagram in astrophysics
With the first detection of gravitational waves from a binary system of neutron stars GW170817, a new window was opened to study the properties of matter at and above nuclear-saturation density. Reaching densities a few times that of nuclear matter and temperatures up to 100 MeV, such mergers also represent potential sites for a phase transition from confined hadronic matter to deconfined...

The first unambiguous observation of a neutron star merger in 2017 has highlighted the prospect to learn about incompletely known properties of neutron stars and high-density matter. We will discuss the impact of the hadron-quark phase transition on observables of neutron star mergers. In turn, future observations of neutron star merger events can be employed to understand whether or not the...

We investigate the effect of the formation of the structured mixed phase (pasta phase) on the quark-hadron phase transition. The results of the full numerical solution with pasta phases are compared with those of an interpolating construction used in previous works, for which we demonstrate an adequate description of the numerical results. For each pair of RMF models for quark and hadron...

We revisit the Polyakov Loop coupled Nambu-Jona-Lasinio model that maintains the Polyakov loop dynamics at zero temperature, which is the most interesting for astrophysical applications. For this purpose we re-examine potential for the deconfinement order parameter at finite baryonic densities. Secondly, and the most important, we explicitly demonstrate that naive modification of this...
