Multi-dimensional NLTE radiative transfer for a double detonation Type Ia explosion model in the photospheric phase

F. P. Callan, L. J. Shingles, S. A. Sim +7

Previous radiative transfer calculations have shown that both multi-dimensionality and NLTE (non local thermodynamic equilibrium) effects impact the synthetic observables predicted…

Non-LTE radiative transfer simulations: Improved agreement of the double detonation with normal Type Ia supernovae

Christine E. Collins, Luke J. Shingles, Stuart A. Sim +6

The double detonation is a widely discussed explosion mechanism for Type Ia supernovae, whereby a helium shell detonation ignites a secondary detonation in the carbon/oxygen core o…

Exploring the range of impacts of helium in the spectra of double detonation models for Type Ia supernovae

F. P. Callan, C. E. Collins, S. A. Sim +7

Models of sub-Chandrasekhar mass double detonations for Type Ia supernovae (SNe Ia) suggest a distinguishing property of this scenario is unburnt helium in the outer ejecta. Howeve…

Helium as a signature of the double detonation in Type Ia supernovae

Christine E. Collins, Stuart A. Sim, Luke. J. Shingles +5

The double detonation is a widely discussed mechanism to explain Type Ia supernovae from explosions of sub-Chandrasekhar mass white dwarfs. In this scenario, a helium detonation is…

Double detonations: variations in Type Ia supernovae due to different core and He shell masses -- II: synthetic observables

Christine E. Collins, Sabrina Gronow, Stuart A. Sim +1

Double detonations of sub-Chandrasekhar mass white dwarfs are a promising explosion scenario for Type Ia supernovae, whereby a detonation in a surface helium shell triggers a secon…

Metallicity-dependent nucleosynthetic yields of Type Ia supernovae originating from double detonations of sub-M white dwarfs

Sabrina Gronow, Benoit Cote, Florian Lach +4

Double detonations in sub-Chandrasekhar mass carbon-oxygen white dwarfs with helium shell are a potential explosion mechanism for a Type Ia supernova (SNe Ia). It comprises a shell…

Double detonations of sub-Chandrasekhar mass CO white dwarfs: Can different core and He shell masses explain variations of Type Ia supernovae?

Sabrina Gronow, Christine E. Collins, Stuart A. Sim +1

Sub-Chandrasekhar mass carbon-oxygen white dwarfs (CO WDs) with a surface helium (He) shell have been proposed as progenitors of Type Ia supernovae (SNe Ia). If true, the resulting…

Nucleosynthesis imprints from different Type Ia Supernova explosion scenarios and implications for galactic chemical evolution

F. Lach, F. K. Roepke, I. R. Seitenzahl +3

We analyze the nucleosynthesis yields of various Type Ia supernova explosion simulations including pure detonations in sub- Chandrasekhar mass white dwarfs, double detonations and…

SNe Ia from double detonations: Impact of core-shell mixing on the carbon ignition mechanism

Sabrina Gronow, Christine Collins, Sebastian T. Ohlmann +5

Sub-Chandrasekhar mass white dwarfs accreting a helium shell on a carbon-oxygen core are potential progenitors of normal Type Ia supernovae. This work focuses on the details of the…
