Type Ia Supernova Nucleosynthesis: Metallicity-Dependent Yields
James D Keegans, Marco Pignatari, Richard J Stancliffe +7
Type Ia supernova explosions (SNIa) are fundamental sources of elements for the chemical evolution of galaxies. They efficiently produce intermediate-mass (with Z between 11 and 20…
Multi-Dimensional Parameter Study of Double Detonation Type Ia Supernovae Originating from Thin-Helium-Shell White Dwarfs
Samuel J. Boos, Dean M. Townsley, Ken J. Shen +2
Despite the importance of Type Ia supernovae (SNe Ia) throughout astronomy, the precise progenitor systems and explosion mechanisms that drive SNe Ia are still unknown. An explosio…
Modeling subgrid combustion processes in simulations of thermonuclear supernovae
Dean M. Townsley, Alan C. Calder, Broxton J. Miles
Supernovae of type Ia are thought to arise from the thermonuclear incineration of a carbon-oxygen white dwarf stellar remnant. However, the detailed explosion scenario and stellar…
Double Detonations with Thin, Modestly Enriched Helium Layers Can Make Normal Type Ia Supernovae
Dean M. Townsley, Broxton J. Miles, Ken J. Shen +1
It has been proposed that Type Ia supernovae (SNe Ia) that are normal in their spectra and brightness can be explained by a double detonation that ignites first in a helium shell o…
Quantifying How Density Gradients and Front Curvature Affect Carbon Detonation Strength During Type Ia Supernovae
Broxton J. Miles, Dean M. Townsley, Ken J. Shen +2
Accurately reproducing the physics behind the detonations of Type Ia supernovae and the resultant nucleosynthetic yields is important for interpreting observations of spectra and r…
Three Hypervelocity White Dwarfs in Gaia DR2: Evidence for Dynamically Driven Double-Degenerate Double-Detonation Type Ia Supernovae
Ken J. Shen, Douglas Boubert, Boris T. Gänsicke +23
Double detonations in double white dwarf (WD) binaries undergoing unstable mass transfer have emerged in recent years as one of the most promising Type Ia supernova (SN Ia) progeni…
Sub-Chandrasekhar-mass white dwarf detonations revisited
Ken J. Shen, Daniel Kasen, Broxton J. Miles +1
The detonation of a sub-Chandrasekhar-mass white dwarf (WD) has emerged as one of the most promising Type Ia supernova (SN Ia) progenitor scenarios. Recent studies have suggested t…
Observational evidence for high neutronization in supernova remnants: implications for Type Ia supernova progenitors
Héctor Martínez-Rodríguez, Carles Badenes, Hiroya Yamaguchi +8
The physical process whereby a carbon--oxygen white dwarf explodes as a Type Ia supernova (SN Ia) remains highly uncertain. The degree of neutronization in SN Ia ejecta holds clues…
Cosmic Chandlery with Thermonuclear Supernovae
Alan C. Calder, Brendan K. Krueger, Aaron P. Jackson +3
Thermonuclear (Type Ia) supernovae are bright stellar explosions, the light curves of which can be calibrated to allow for use as "standard candles" for measuring cosmological dist…
A Tracer Method for Computing Type Ia Supernova Yields: Burning Model Calibration, Reconstruction of Thickened Flames, and Verification for Planar Detonations
Dean M. Townsley, Broxton J. Miles, F. X. Timmes +2
We refine our previously introduced parameterized model for explosive carbon-oxygen fusion during thermonuclear supernovae (SN Ia) by adding corrections to post-processing of recor…
On Measuring the Metallicity of a Type Ia Supernova's Progenitor
Broxton J. Miles, Daniel R. van Rossum, Dean M. Townsley +4
In Type Ia Supernovae (\sneia), the relative abundances of chemical elements are affected by the neutron excess in the composition of the progenitor white dwarf. Since these produc…
