Multi-wavelength Signatures of Supernova Shock Breakout from Red Supergiants in Two Dimensions
Wun-Yi Chen, Ke-Jung Chen, Keiichi Maeda +3
We present new two-dimensional radiation hydrodynamic simulations of supernova shock breakout from red supergiants using the code. Our progenitors are 20 and 25 M…
The role of the secondary white dwarf in a double-degenerate double-detonation explosion, in the supernova remnant phase
Gilles Ferrand, Rüdiger Pakmor, Yusei Fujimaru +7
Type Ia supernovae (SNe) are believed to be thermonuclear explosions of white dwarf (WD) stars, but their progenitor systems and explosion mechanisms are still unclear. Here we foc…
NLTE spectral modelling for a carbon-oxygen and helium white-dwarf merger as a Ca-rich transient candidate
F. P. Callan, A. Holas, J. Morán-Fraile +7
We carry out NLTE (non local thermodynamic equilibrium) radiative transfer simulations to determine whether explosion during the merger of a carbon-oxygen (CO) white dwarf (WD) wit…
Modelling the ionisation state of Type Ia supernovae in the nebular-phase
Luke J. Shingles, Andreas Flörs, Stuart A. Sim +4
The nebular spectra of Type Ia supernovae ( 100 days after explosion) consist mainly of emission lines from singly- and doubly-ionised Fe-group nuclei. However, theoret…
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…
From supernova to supernova remnant: comparison of thermonuclear explosion models
Gilles Ferrand, Donald C. Warren, Masaomi Ono +6
Progress in the three-dimensional modeling of supernovae (SN) prompts us to revisit the supernova remnant (SNR) phase. We continue our study of the imprint of a thermonuclear explo…
