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…
The Challenges of Modeling Astrophysical Reacting Flows
Michael Zingale, Khanak Bhargava, Ryan Brady +5
Stellar evolution is driven by the changing composition of a star from nuclear reactions. At the late stages of evolution and during explosive events, the timescale can be short an…
Hydrodynamical simulations of proton ingestion flashes in Type I X-ray Bursts
Simon Guichandut, Michael Zingale, Andrew Cumming
We perform the first multidimensional fluid simulations of thermonuclear helium ignition underneath a hydrogen-rich shell. This situation is relevant to Type I X-ray bursts on neut…
Strong Coupling of Hydrodynamics and Reactions in Nuclear Statistical Equilibrium for Modeling Convection in Massive Stars
Michael Zingale, Zhi Chen, Eric T. Johnson +2
We build on the simplified spectral deferred corrections (SDC) coupling of hydrodynamics and reactions to handle the case of nuclear statistical equilibrium (NSE) and electron/posi…
Simulating Lateral H/He Flame Propagation in Type I X-ray Bursts
Eric T. Johnson, Michael Zingale
X-ray bursts are the thermonuclear runaway of a mixed H/He layer on the surface of a neutron star. Observations suggest that the burning begins locally and spreads across the surfa…
