Observational signatures of thermonuclear electron-capture supernovae -- Ne II line strengthening and color evolution as traces of the explosion mechanism

Alexander Holas, Fionntan P. Callan, Samuel W. Jones +7

Thermonuclear electron-capture supernovae (tECSNe) are a potential fate of certain intermediate mass stars forming ONe cores at the end of their evolution. Simulations suggest that…

The asymmetry of white dwarf double detonations and the observed scatter around the Phillips relation

Alexander Holas, Friedrich K. Roepke, Rüdiger Pakmor +6

Recent Type Ia supernova (SN Ia) simulations featuring a double detonation scenario have managed to reproduce the overall trend of the Phillips relation reasonably well. However, m…

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…

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…

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…

On the fate of the secondary white dwarf in double-degenerate double-detonation Type Ia supernovae

R. Pakmor, F. P. Callan, C. E. Collins +12

The progenitor systems and explosion mechanism of Type Ia supernovae are still unknown. Currently favoured progenitors include double-degenerate systems consisting of two carbon-ox…
