Phenomenological quark-hadron equations of state with first-order phase transitions for astrophysical applications
Niels-Uwe F. Bastian
In the current work an equation of state model with a first-order phase transition for astrophysical applications is presented. The model is based on a two-phase approach for quark…
Medium modifications for light and heavy nuclear clusters in simulations of core collapse supernovae -- Impact on equation of state and weak interactions
Tobias Fischer, Stefan Typel, Gerd Röpke +2
The present article investigates the role of heavy nuclear clusters and weakly bound light nuclear clusters based on a newly developed equation of state for core collapse supernova…
Constraining the onset density of the hadron-quark phase transition with gravitational-wave observations
Sebastian Blacker, Niels-Uwe F. Bastian, Andreas Bauswein +5
We study the possible occurrence of the hadron-quark phase transition (PT) during the merging of neutron star binaries by hydrodynamical simulations employing a set of temperature…
Equation of state constraints from the threshold binary mass for prompt collapse of neutron star mergers
Andreas Bauswein, Sebastian Blacker, Vimal Vijayan +7
Using hydrodynamical simulations for a large set of high-density matter equations of state (EoSs) we systematically determine the threshold mass M_thres for prompt black-hole forma…
Core-collapse Supernova Explosions Driven by the Hadron-quark Phase Transition as a Rare -process Site
Tobias Fischer, Meng-Ru Wu, Benjamin Wehmeyer +3
Supernova explosions of massive stars are one of the primary sites for the production of the elements in the universe. Up to now, stars with zero-age main-sequence masses in the ra…
Impact of the Nuclear Equation of State on the Stability of Hybrid Neutron Stars
Mateusz Cierniak, Tobias Fischer, Niels-Uwe Bastian +2
We construct a set of equations of state (EoS) of dense and hot matter with a 1st order phase transition from a hadronic system to a deconfined quark matter state. In this two-phas…
