  1. Stellar interior convection:Hydrodynamics and Mixing of He-shell Flash Convection Pressure fluctuations with pseudo-streamlines overplotted, 2D, 1200x600, enhanced heating (30x) (lc0gh)

  2. s-process in hydrodynamic convection simulations Eulerian trajectories: Temperature evolutions: High-temperature s-process nucleosynthesis driven by the 22Ne neutron source in the He-shell flash convection zone along trajectories from hydrdoynamics simulation. Branchings, T-dependent on convective turnover time scale. • Requires: • updated s-process network with T-dependent -decays and n-capture cross sections (Marco Pignatari) • n-cross sections for unstable species (Reifarth etal @ LANSCE/GSI) • New parallel code for general post-processing: ppn, tppn, mppn
