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…
Muonization of supernova matter
Tobias Fischer, Gang Guo, Gabriel Martínez-Pinedo +2
The present article investigates the impact of muons on core-collapse supernovae, with particular focus on the early muon neutrino emission. While the presence of muons is well und…
Heavy axion-like particles and core-collapse supernovae: constraints and impact on the explosion mechanism
Giuseppe Lucente, Pierluca Carenza, Tobias Fischer +2
Heavy axion-like particles (ALPs), with masses keV, coupled with photons, would be copiously produced in a supernova (SN) core via Primakoff process and photon co…
Charged-Current Muonic Reactions in Core-Collapse Supernovae
Gang Guo, Gabriel Martínez-Pinedo, Andreas Lohs +1
The steady advance in core-collapse supernova simulations requires a more precise description of neutrino processes in hot and dense matter. In this work, we study the rates of cha…
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…
