Simulating the Convective Urca Process with Multiple Urca Pairs in a Simmering White Dwarf
Brendan Boyd, Ferran Poca-Amorós, Alan Calder +1
Type Ia supernovae are bright thermonuclear explosions of one or more white dwarf stars. The exact origin and explosion mechanism for these supernovae is still poorly understood. I…
On the Importance of the Convective Urca Process in 3D Simulations of a Simmering White Dwarf
Ferran Poca-Amorós, Brendan Boyd, Dean M. Townsley +1
Type Ia supernovae are bright thermonuclear explosions that are important to numerous areas of astronomy. However, the origins of these events are poorly understood. One proposed s…
3D Convective Urca Process in a Simmering White Dwarf
Brendan Boyd, Alan Calder, Dean Townsley +1
A proposed setting for thermonuclear (Type Ia) supernovae is a white dwarf that has gained mass from a companion to the point of carbon ignition in the core. In the early stages of…
Sensitivity of 3D Convective Urca Simulations to Changes in Urca Reactions
Brendan Boyd, Alexander Smith Clark, Alan C. Calder +2
A proposed setting for thermonuclear (Type Ia) supernovae is a white dwarf that has gained mass from a companion to the point of carbon ignition in the core. There is a simmering p…
Three-Dimensional Simulations of the Deflagration Phase of the Gravitationally Confined Detonation Model of Type Ia Supernovae
G C Jordan, R T Fisher, D M Townsley +5
We report the results of a series of three-dimensional (3-D) simulations of the deflagration phase of the gravitationally confined detonation mechanism for Type Ia supernovae. In t…
Type Ia Supernova Explosion: Gravitationally Confined Detonation
Tomasz Plewa, Alan Calder, Don Lamb
We present a new mechanism for Type Ia supernova explosions in massive white dwarfs. The proposed scenario follows from relaxing the assumption of symmetry in the model and involve…
