Astrophysical Reaction Rates for Charged-Particle Induced Reactions on Proton-Rich Nuclides
Thomas Rauscher
Astrophysical reaction rates for reactions with proton-rich isotopes of Ne to Bi from stability to the proton dripline were calculated with an updated version of the SMARAGD statis…
Stellar neutron capture reactions at low and high temperature
Thomas Rauscher
The determination of astrophysical reaction rates requires different approaches depending on the conditions in hydrostatic and explosive burning. The focus here is on astrophysical…
Asymmetric Nuclear Light Clusters In Supernova Matter
Andrey Yudin, Matthias Hempel, Sergei Blinnikov +2
We explore the appearance of light clusters at high densities of collapsing stellar cores. Special attention is paid to the unstable isotope H4, which was not included in previous…
A new temperature dependent hyperonic equation of state: application to rotating neutron star models and I-Q-relations
Miguel Marques, Micaela Oertel, Matthias Hempel +1
In this work we present a newly constructed equation of state (EoS) --applicable to stellar core collapse and neutron star mergers--, including the entire baryon octet. Our EoS is…
Phase transitions in dense matter
Veronica Dexheimer, Matthias Hempel, Igor Iosilevskiy +1
As the density of matter increases, atomic nuclei disintegrate into nucleons and, eventually, the nucleons themselves disintegrate into quarks. The phase transitions (PT's) between…
How Well Do We Know The Supernova Equation of State?
Matthias Hempel, Micaela Oertel, Stefan Typel +1
We give an overview about equations of state (EOS) which are currently available for simulations of core-collapse supernovae and neutron star mergers. A few selected important aspe…
Consequences of simultaneous chiral symmetry breaking and deconfinement for the isospin symmetric phase diagram
Tobias Fischer, Thomas Klähn, Matthias Hempel
The thermodynamic bag model (tdBag) has been applied widely to model quark matter properties in both heavy-ion and astrophysics communities. Several fundamental physics aspects are…
Simultaneous chiral symmetry restoration and deconfinement - Consequences for the QCD phase diagram
Thomas Klahn, Tobias Fischer, Matthias Hempel
For studies of quark matter in astrophysical scenarios the thermodynamic bag model (tdBag) is commonly employed. Although successful, it does not account for dynamical chiral symme…
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.…
The neutron skin thickness from the measured electric dipole polarizability in Ni, Sn, and Pb
X. Roca-Maza, X. Viñas, M. Centelles +5
The information on the symmetry energy and its density dependence is deduced by comparing the available data on the electric dipole polarizability of Ni, S…
Hybrid method to resolve the neutrino mass hierarchy by supernova (anti)neutrino induced reactions
D. Vale, T. Rauscher, N. Paar
We introduce a hybrid method to determine the neutrino mass hierarchy by simultaneous measurements of responses of at least two detectors to antineutrino and neutrino fluxes from a…
Nuclear Reactions For Nucleosynthesis Beyond Fe
T. Rauscher
Many more nuclear transitions have to be known in the determination of stellar reactivities for trans-iron nucleosynthesis than for reactions of light nuclei. This requires differe…
Modeling nuclear weak-interaction processes with relativistic energy density functionals
N. Paar, T. Marketin, D. Vale +1
Relativistic energy density functionals have become a standard framework for nuclear structure studies of ground-state properties and collective excitations over the entire nuclide…
Electromagnetic Structure of Few-Nucleon Ground States
L. E. Marcucci, F. Gross, M. T. Pena +6
Experimental form factors of the hydrogen and helium isotopes, extracted from an up-to-date global analysis of cross sections and polarization observables measured in elastic elect…
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…
Nucleon self-energies for supernova equations of state
Matthias Hempel
Nucleon self-energies and interaction potentials in supernova (SN) matter, which are known to have an important effect on nucleosynthesis conditions in SN ejecta are investigated.…
Resolving neutrino mass hierarchy from supernova (anti)neutrino-nucleus reactions
Deni Vale, Nils Paar
We introduce a hybrid method to determine neutrino mass hierarchy by simultaneous measurements of detector responses induced by antineutrino and neutrino fluxes from accretion and…
Asymmetric Neutrino Production in Strongly Magnetized Proto-Neutron Stars
Tomoyuki Maruyama, Myung-Ki Cheoun, Jun Hidaka +6
We calculate the neutrino production cross-section through the direct URCA process in proto-neutron star matter in the presence of a strong magnetic field. We assume isoentropic co…

J. J. He, A. Parikh, B. A. Brown +5
The thermonuclear rate of the Ti(,)V reaction has been reevaluated based on a recent precise proton separation energy measurement of (V)=8343 k…
Nuclear Masses and Neutron Stars
Susanne Kreim, Matthias Hempel, David Lunney +1
Precision mass spectrometry of neutron-rich nuclei is of great relevance for astrophysics. Masses of exotic nuclides impose constraints on models for the nuclear interaction and th…
Non-congruence of the nuclear liquid-gas and deconfinement phase transitions
Matthias Hempel, Veronica Dexheimer, Stefan Schramm +1
First order phase transitions (PTs) with more than one globally conserved charge, so-called non-congruent PTs, have characteristic differences compared to congruent PTs (e.g., dime…
A comparative study of statistical models for nuclear equation of state of stellar matter
N. Buyukcizmeci, A. S. Botvina, I. N. Mishustin +8
We compare three different statistical models for the equation of state (EOS) of stellar matter at subnuclear densities and temperatures (0.5-10 MeV) expected to occur during the c…
