Modeling of the nebular-phase spectral evolution of stripped-envelope supernovae. New grids from 100 to 450 days
Luc Dessart, D. John Hillier, S. E. Woosley +1
We present an extended grid of multi-epoch 1D nonlocal thermodynamic equilibrium radiative transfer calculations for nebular-phase Type Ibc supernovae (SNe) from He-star explosions…
StaNdaRT: A repository of standardized test models and outputs for supernova radiative transfer
Stéphane Blondin, Sergei Blinnikov, Fionntan P. Callan +26
We present the first results of a comprehensive supernova (SN) radiative-transfer (RT) code-comparison initiative (StaNdaRT), where the emission from the same set of standardized t…
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…
The Pair-Instability Mass Gap for Black Holes
S. E. Woosley, Alexander Heger
Stellar evolution theory predicts a "gap" in the black hole birth function caused by the pair instability. Presupernova stars that have a core mass below some limiting value, Mlo,…
The Evolution of Massive Helium Stars Including Mass Loss
S. E. Woosley
The evolution of helium stars with initial masses in the range 1.6 to 120 Msun is studied, including the effects of mass loss by winds. These stars are assumed to form in binary sy…
