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…
Exploring the origins of high-velocity features in SNe Ia with the spectral synthesis code TARDIS
Luke Harvey, Kate Maguire, Alexander Holas +8
Appearing as secondary higher-velocity absorption components, high-velocity features (HVFs) have been observed in several absorption lines in many Type Ia supernovae (SNe Ia). The…
Multidimensional Nebular-Phase Calculations of Dynamically-Driven Double-Degenerate Double-Detonation Models for Type Ia Supernovae
J. M. Pollin, S. A. Sim, L. J. Shingles +7
The dynamically-driven double-degenerate double-detonation model has emerged as a promising progenitor candidate for Type Ia supernovae. In this scenario, the primary white dwarf i…
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…
