Constraining the onset density for the QCD phase transition with the neutrino signal from core-collapse supernovae
Noshad Khosravi Largani, Tobias Fischer, Niels Uwe F. Bastian
The occurrence of a first-order hadron-quark matter phase transition at high baryon densities is investigated in astrophysical simulations of core-collapse supernovae, to decipher…
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…
Equation-of-state Constraints and the QCD Phase Transition in the Era of Gravitational-Wave Astronomy
Andreas Bauswein, Niels-Uwe Friedrich Bastian, David Blaschke +7
We describe a multi-messenger interpretation of GW170817, which yields a robust lower limit on NS radii. This excludes NSs with radii smaller than about 10.7 km and thus rules out…
Identifying a first-order phase transition in neutron star mergers through gravitational waves
Andreas Bauswein, Niels-Uwe F. Bastian, David B. Blaschke +4
We identify an observable imprint of a first-order hadron-quark phase transition at supranuclear densities on the gravitational-wave (GW) emission of neutron star mergers. Specific…
Quark deconfinement as supernova explosion engine for massive blue-supergiant stars
Tobias Fischer, Niels-Uwe F. Bastian, Meng-Ru Wu +6
Blue-supergiant stars develop into core-collapse supernovae --- one of the most energetic outbursts in the universe --- when all nuclear burning fuel is exhausted in the stellar co…
The state of matter in simulations of core-collapse supernovae -- Reflections and recent developments
Tobias Fischer, Niels-Uwe Bastian, David Blaschke +7
In this review article we discuss selected developments regarding the role of the equation of state (EOS) in simulations of core-collapse supernovae. There are no first-principle c…
Strange matter prospects within the string-flip model
Niels-Uwe F. Bastian, David B. Blaschke, Mateusz Cierniak +4
In this contribution we extend the recently developed two-flavor quark-matter string-flip model by including strange quarks. We discuss implications for compact stars.
Quark-Nuclear Hybrid EoS with Excluded Volume Effects
Mark Alexander Randolph Kaltenborn, Niels-Uwe Friedrich Bastian, David Bernhard Blaschke
A two-phase description of the quark-nuclear matter hybrid equation of state that takes into account the effect of excluded volume in both the hadronic and the quark matter phases…
