One-dimensional delayed-detonation models of Type Ia supernovae: Confrontation to observations at bolometric maximum
Stéphane Blondin, Luc Dessart, D. John Hillier +1
The delayed-detonation explosion mechanism applied to a Chandrasekhar-mass white dwarf offers a very attractive model to explain the inferred characteristics of Type Ia supernovae…
Radiative Properties of Pair-instability Supernova Explosions
Luc Dessart, Roni Waldman, Eli Livne +2
We present non-LTE time-dependent radiative-transfer simulations of pair-instability supernovae (PISNe) stemming from red-supergiant (RSG), blue-supergiant (BSG) and Wolf-Rayet (WR…
Super-luminous supernovae: 56Ni power versus magnetar radiation
Luc Dessart, D. John Hillier, Roni Waldman +2
Much uncertainty surrounds the origin of super-luminous supernovae (SNe). Motivated by the discovery of the Type Ic SN2007bi, we study its proposed association with a pair-instabil…
Non-thermal excitation and ionization in supernovae
Chengdong Li, D. John Hillier, Luc Dessart
We incorporate non-thermal excitation and ionization processes arising from non-thermal electrons that result from γ-ray energy deposition, into our radiative transfer code CMFGEN.…
On the nature of supernovae Ib and Ic
Luc Dessart, D. John Hillier, Chengdong Li +1
Using non-LTE time-dependent radiative-transfer calculations, we study the impact of mixing and non-thermal processes associated with radioactive decay on SN IIb/Ib/Ic light curves…
Time Dependent Radiative Transfer Calculations for Supernovae
D. John Hillier, Luc Dessart
In previous papers we discussed results from fully time-dependent radiative transfer models for core-collapse supernova (SN) ejecta, including the Type II-peculiar SN 1987A, the mo…
