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…
Synthetic Light Curves and Spectra for the Photospheric Phase of a 3D Stripped-Envelope Supernova Explosion Model
Thomas Maunder, Fionntan P. Callan, Stuart A. Sim +2
We present synthetic light curves and spectra from three-dimensional (3D) Monte Carlo radiative transfer simulations based on a 3D core-collapse supernova explosion model of an ult…
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…
On the fate of the secondary white dwarf in double-degenerate double-detonation Type Ia supernovae -- II. 3D synthetic observables
J. M. Pollin, S. A. Sim, R. Pakmor +5
A leading model for Type Ia supernovae involves the double-detonation of a sub-Chandrasekhar mass white dwarf. Double-detonations arise when a surface helium shell detonation gener…
Including a Luminous Central Remnant in Radiative Transfer Simulations for Type Iax Supernovae
F. P. Callan, S. A. Sim, C. E. Collins +6
Type Iax supernovae (SNe Iax) are proposed to arise from deflagrations of Chandrasekhar mass white dwarfs (WDs). Previous deflagration simulations have achieved good agreement with…
