Dynamics of Laterally Propagating Flames in X-ray Bursts. I. Burning Front Structure
Kiran Eiden, Michael Zingale, Alice Harpole +3
We investigate the structure of laterally-propagating flames through the highly-stratified burning layer in an X-ray burst. Two-dimensional hydrodynamics simulations of flame propa…
Modelling low Mach number stellar hydrodynamics with MAESTROeX
A. Harpole, D. Fan, M. P. Katz +3
Modelling long-time convective flows in the interiors of stars is extremely challenging using conventional compressible hydrodynamics codes due to the acoustic timestep limitation.…
The Castro AMR Simulation Code: Current and Future Developments
M. Zingale, A. S. Almgren, M. Barrios Sazo +7
We describe recent developments to the Castro astrophysics simulation code, focusing on new features that enable our simulations of X-ray bursts. Two highlights of Castro's ongoing…
Improved Coupling of Hydrodynamics and Nuclear Reactions via Spectral Deferred Corrections
M. Zingale, M. P. Katz, J. B. Bell +3
Simulations in stellar astrophysics involve the coupling of hydrodynamics and nuclear reactions under a wide variety of conditions, from simmering convective flows to explosive nuc…
Comments on "Numerical Stability of Detonations in White Dwarf Simulations"
Doron Kushnir, Boaz Katz
Katz & Zingale (2019, KZ19) recently studied a one-dimensional test problem, intended to mimic the process of detonation ignition in head-on collisions of two carbon--oxygen (CO) w…
Numerical Stability of Detonations in White Dwarf Simulations
Max P. Katz, Michael Zingale
Some simulations of Type Ia supernovae feature self-consistent thermonuclear detonations. However, these detonations are not meaningful if the simulations are not resolved, so it i…
