Noncongruence of phase transitions in strongly interacting matter
Matthias Hempel, Veronica Dexheimer, Stefan Schramm +1
First-order phase transitions (PTs) with more than one globally conserved charge, so-called noncongruent PTs, have characteristic differences compared to congruent PTs (e.g., dimen…
Expected impact from weak reactions with light nuclei in core-collapse supernova simulations
T. Fischer, G. Martínez-Pinedo, M. Hempel +4
We study the role of light nuclear clusters in simulations of core-collapse supernovae. Expressions for the reaction rates are developed for a large selection of charged current ab…
Hot third family of compact stars and the possibility of core-collapse supernova explosions
Matthias Hempel, Oliver Heinimann, Andrey Yudin +3
A phase transition to quark matter can lead to interesting phenomenological consequences in core-collapse supernovae, e.g., triggering an explosion in spherically symmetric models.…
Some properties of convection in hybrid stars
A. V. Yudin, M. Hempel, D. K. Nadyozhin +1
It is shown that the unusual thermodynamic properties of matter within the region of two-phase coexistence in hybrid stars result in a change of the standard condition for beginnin…
Two-Dimensional Core-Collapse Supernova Simulations with the Isotropic Diffusion Source Approximation for Neutrino Transport
Kuo-Chuan Pan, Matthias Liebendörfer, Matthias Hempel +1
The neutrino mechanism of core-collapse supernova is investigated via non-relativistic, two-dimensional (2D), neutrino radiation-hydrodynamic simulations. For the transport of elec…
Constraining supernova equations of state with equilibrium constants from heavy-ion collisions
Matthias Hempel, Kris Hagel, Joseph Natowitz +2
Cluster formation is a fundamental aspect of the equation of state (EOS) of warm and dense nuclear matter such as can be found in supernovae (SNe). Similar matter can be studied in…
