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…

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…
