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.…
The i-process yields of rapidly-accreting white dwarfs from multicycle He-shell flash stellar evolution models with mixing parameterizations from 3D hydrodynamics simulations
Pavel Denissenkov, Falk Herwig, Paul Woodward +3
We have modelled the multicycle evolution of rapidly-accreting CO white dwarfs (RAWDs) with stable H burning intermittent with strong He-shell flashes on their surfaces for $0.7\le…
3D hydrodynamic simulations of C ingestion into a convective O shell
Robert Andrassy, Falk Herwig, Paul Woodward +1
Interactions between convective shells in evolved massive stars have been linked to supernova impostors, to the production of the odd-Z elements Cl, K, and Sc, and they might also…
Cyberhubs: Virtual Research Environments for Astronomy
Falk Herwig, Robert Andrassy, Nic Annau +9
Collaborations in astronomy and astrophysics are faced with numerous cyber infrastructure challenges, such as large data sets, the need to combine heterogeneous data sets, and the…
