Multidimensional low-Mach number time-implicit hydrodynamic simulations of convective helium shell burning in a massive star
L. Horst, R. Hirschi, P. V. F. Edelmann +2
Context. Multidimensional hydrodynamic simulations of convection in stellar interiors are numerically challenging, especially for flows at low Mach numbers. Methods. We explore the…
Well-balanced treatment of gravity in astrophysical fluid dynamics simulations at low Mach numbers
P. V. F. Edelmann, L. Horst, J. P. Berberich +5
Accurate simulations of flows in stellar interiors are crucial to improving our understanding of stellar structure and evolution. Because the typically slow flows are merely tiny p…
Fully compressible simulations of waves and core convection in main-sequence stars
L. Horst, P. V. F. Edelmann, R. Andrassy +4
Context. Recent, nonlinear simulations of wave generation and propagation in full-star models have been carried out in the anelastic approximation using spectral methods. Although…
3D1D hydro-nucleosynthesis simulations. I. Advective-reactive post-processing method and its application to H ingestion into He-shell flash convection in rapidly accreting white dwarfs
David Stephens, Falk Herwig, Paul Woodward +3
We present two mixing models for post-processing of 3D hydrodynamic simulations applied to convective-reactive i-process nucleosynthesis in a rapidly accreting white dwarf (RAWD) w…
Simulating 3-D Stellar Hydrodynamics using PPM and PPB Multifluid Gas Dynamics on CPU and CPU+GPU Nodes
Paul R. Woodward, Pei-Hung Lin, Huaqing Mao +2
The special computational challenges of simulating 3-D hydrodynamics in deep stellar interiors are discussed, and numerical algorithmic responses described. Results of recent simul…
H-He Shell Interactions and Nucleosynthesis in Massive Population III Stars
Ondrea Clarkson, Falk Herwig, Robert Andrassy +3
We report on our ongoing investigation into the nucleosynthetic and hydrodynamic nature of mixing at the interface between the H- and He-convection zones in massive Pop III stars.…
