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…

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.…
