Nebular phase properties of supernova Ibc from He-star explosions
L. Dessart, D. J. Hillier, T. Sukhbold +2
Following our recent work on Type II supernovae (SNe), we present a set of 1D nonlocal thermodynamic equilibrium radiative transfer calculations for nebular-phase Type Ibc SNe star…
The explosion of 929 stars as Type II supernovae : results from radiative-transfer modeling at one year after explosion
Luc Dessart, D. John Hillier, Tuguldur Sukhbold +2
We present a set of nonlocal thermodynamic equilibrium steady-state calculations of radiative transfer for one-year old type II supernovae (SNe) starting from state-of-the-art expl…
Emission line models for the lowest-mass core collapse supernovae. I: Case study of a 9 one-dimensional neutrino-driven explosion
A. Jerkstrand, T. Ertl, H. -T. Janka +3
A large fraction of core-collapse supernovae (CCSNe), 30-50%, are expected to originate from the low-mass end of progenitors with . However, degeneracy…
Simulations of Electron Capture and Low-Mass Iron Core Supernovae
B. Müller, S. Wanajo, H. -Th. Janka +3
The evolutionary pathways of core-collapse supernova progenitors at the low-mass end of the spectrum are beset with major uncertainties. In recent years, a variety of evolutionary…
Light curve analysis of ordinary type IIP supernovae based on neutrino-driven explosion simulations in three dimensions
V. P. Utrobin, A. Wongwathanarat, H. -Th. Janka +1
Type II-plateau supernovae (SNe IIP) are the most numerous subclass of core-collapse SNe originating from massive stars. In the framework of the neutrino-driven explosion mechanism…
Solar r-process-constrained actinide production in neutrino-driven winds of supernovae
S. Goriely, H. -Th. Janka
Long-lived radioactive nuclei play an important role as nucleo-cosmochronometers and as cosmic tracers of nucleosynthetic source activity. In particular nuclei in the actinide regi…
Nucleosynthesis constraints on the neutron star-black hole merger rate
Andreas Bauswein, Ricard Ardevol Pulpillo, H. -Thomas Janka +1
We derive constraints on the time-averaged event rate of neutron star-black hole (NS-BH) mergers by using estimates of the population-integrated production of heavy rapid neutron-c…
Parametrized 3D models of neutrino-driven supernova explosions: Neutrino emission asymmetries and gravitational-wave signals
E. Müller, H. -Th. Janka, A. Wongwathanarat
Time-dependent and direction-dependent neutrino and gravitational-wave (GW) signatures are presented for a set of 3D hydrodynamic models of parametrized, neutrino-driven supernova…
