Emission line models for the lowest mass core-collapse supernovae -- II. 3D NLTE radiative transfer modelling of a neutrino-driven explosion
Bart F. A. van Baal, Anders Jerkstrand, Daniel Kresse +1
The nebular phase of a supernova (SN) occurs several months to years after the explosion, with asymmetries created by the explosion encoded into the line profiles of the emission l…
Stripped-Envelope Supernovae for QCD Axion Detection
Francisco R. Candón, Damiano F. G. Fiorillo, Ãngel Gil Muyor +3
QCD axions would be copiously produced in the proto-neutron star formed in a core-collapse supernova (SN). After escaping, they would convert into gamma rays in the Galactic magnet…
Gravitational-Wave Signals for Supernova Explosions of Three-Dimensional Progenitors
Alessandro Lella, Giuseppe Lucente, Daniel Kresse +3
Core-collapse supernovae (SNe) are sources of gravitational waves (GWs) produced by hydrodynamical instabilities and highly time-dependent anisotropies of the neutrino radiation. I…
Neutrinos from core-collapse supernovae
Georg G. Raffelt, Hans-Thomas Janka, Damiano F. G. Fiorillo
The core of a massive star (M > 8 Msun) eventually collapses. This implosion usually triggers a supernova (SN) explosion that ejects most of the stellar envelope and leaves behind…
Axion-photon conversion in transient compact stars: Systematics, constraints, and opportunities
Damiano F. G. Fiorillo, Ãngel Gil Muyor, Hans-Thomas Janka +2
We study magnetic conversion of ultra-relativistic axion-like particles (ALPs) into photons in compact-star environments, focusing on the hot, transient conditions of core-collapse…
Long-Term Multidimensional Models of Core-Collapse Supernovae: Progress and Challenges
H. -Thomas Janka
Self-consistent, multidimensional core-collapse supernova (SN) simulations, especially in 3D, have achieved tremendous progress over the past 10 years. They are now able to follow…
