Supernova Simulations Confront SN 1987A Neutrinos
Damiano F. G. Fiorillo, Malte Heinlein, Hans-Thomas Janka +3
We return to interpreting the historical SN~1987A neutrino data from a modern perspective. To this end, we construct a suite of spherically symmetric supernova models with the Prom…
Fast neutrino flavor conversions in one-dimensional core-collapse supernova models with and without muon creation
Francesco Capozzi, Sajad Abbar, Robert Bollig +1
In very dense environments, neutrinos can undergo fast flavor conversions on scales as short as a few centimeters provided that the angular distribution of the neutrino lepton numb…
Self-consistent 3D Supernova Models From -7 Minutes to +7 Seconds: a 1-bethe Explosion of a ~19 Solar-mass Progenitor
R. Bollig, N. Yadav, D. Kresse +3
To date, modern three-dimensional (3D) supernova (SN) simulations have not demonstrated that explosion energies of 10^{51} erg (=1 bethe = 1B) or more are possible for neutrino-dri…
Muons in supernovae: implications for the axion-muon coupling
Robert Bollig, William DeRocco, Peter W. Graham +1
The high temperature and electron degeneracy attained during a supernova allow for the formation of a large muon abundance within the core of the resulting proto-neutron star. If n…
The -process with fully time-dependent supernova neutrino emission spectra
Andre Sieverding, Gabriel Martínez-Pinedo, Karlheinz Langanke +3
The neutrino process that occurs in the outer stellar shells during a supernova explosion and involves neutrino-nucleus reactions produces a range of rare, stable and radioactive i…
Global Comparison of Core-Collapse Supernova Simulations in Spherical Symmetry
Evan O'Connor, Robert Bollig, Adam Burrows +10
We present a comparison between several simulation codes designed to study the core-collapse supernova mechanism. We pay close attention to controlling the initial conditions and i…
Core-collapse supernova simulations in one and two dimensions: comparison of codes and approximations
Oliver Just, Robert Bollig, Hans-Thomas Janka +3
We present spherically symmetric (1D) and axisymmetric (2D) supernova simulations for a convection-dominated 9 Msun and a 20 Msun progenitor that develops violent activity by the s…
Muon Creation in Supernova Matter Facilitates Neutrino-driven Explosions
R. Bollig, H. -Th. Janka, A. Lohs +3
Muons can be created in nascent neutron stars (NSs) due to the high electron chemical potentials and the high temperatures. Because of their relatively lower abundance compared to…
Impact of Nucleon-Nucleon Bremsstrahlung Rates Beyond One-Pion Exchange
Alexander Bartl, Robert Bollig, Hans-Thomas Janka +1
Neutrino-pair production and annihilation through nucleon-nucleon bremsstrahlung is included in current supernova simulations by rates that are based on the one-pion-exchange appro…
Supernova Neutrinos: Production, Oscillations and Detection
Alessandro Mirizzi, Irene Tamborra, Hans-Thomas Janka +5
Neutrinos play a crucial role in the collapse and explosion of massive stars, governing the infall dynamics of the stellar core, triggering and fueling the explosion and driving th…
Neutrino-driven explosion of a 20 solar-mass star in three dimensions enabled by strange-quark contributions to neutrino-nucleon scattering
Tobias Melson, Hans-Thomas Janka, Robert Bollig +3
Interactions with neutrons and protons play a crucial role for the neutrino opacity of matter in the supernova core. Their current implementation in many simulation codes, however,…
