An asymmetric explosion as the origin of spectral evolution diversity in type Ia supernovae
K. Maeda, S. Benetti, M. Stritzinger +10
Type Ia Supernovae (SNe Ia) form an observationally uniform class of stellar explosions, in that more luminous objects have smaller decline-rates. This one-parameter behavior allow…
Double-detonation sub-Chandrasekhar supernovae: synthetic observables for minimum helium shell mass models
M. Kromer, S. A. Sim, M. Fink +3
Abridged. In the double detonation scenario for Type Ia supernovae (SNe Ia) a detonation initiates in a shell of He-rich material accreted from a companion star by a sub-Chandrasek…
Nucleosynthesis in thermonuclear supernovae with tracers: convergence and variable mass particles
Ivo Rolf Seitenzahl, Friedrich Röpke, Michael Fink +1
Nucleosynthetic yield predictions for multi-dimensional simulations of thermonuclear supernovae generally rely on the tracer particle method to obtain isotopic information of the e…
Detonations in Sub-Chandrasekhar Mass C+O White Dwarfs
S. A. Sim, F. K. Roepke, W. Hillebrandt +5
Explosions of sub-Chandrasekhar-mass white dwarfs are one alternative to the standard Chandrasekhar-mass model of Type Ia supernovae. They are interesting since binary systems with…
Nucleosynthesis in Two-Dimensional Delayed Detonation Models of Type Ia Supernova Explosions
K. Maeda, F. K. Roepke, M. Fink +3
The nucleosynthetic characteristics of various explosion mechanisms of Type Ia supernovae (SNe Ia) is explored based on three two-dimensional explosion simulations representing ext…
Double-detonation sub-Chandrasekhar supernovae: can minimum helium shell masses detonate the core?
M. Fink, F. K. Roepke, W. Hillebrandt +3
The explosion of sub-Chandrasekhar mass white dwarfs via the double detonation scenario is a potential explanation for type Ia supernovae. In this scenario, a surface detonation in…
