Convective-reactive Proton-C12 Combustion in Sakurai's Object (V4334 Sagittarii) and Implications for the Evolution and Yields from the First Generations of Stars

Project summary
We perform multi-zone nucleosynthesis simulations based on a one-dimensional stellar evolution model of Sakurai's object, a post-AGB stars that has experienced a He-shell flash during the young white dwarf stage. The simulation results, including ehavy elements like Rb, Sr, Ba and La are compared to observations of this particular object, and important conclusions and constraints for the hydrodynamic nature and the physics of H-ingestion flashes and convective-reactive episodes in stellar environments are reached.
About the simulation codes
We used the stellar evolution code EVOL, the NuGrid nucleosynthesis codes and the PPMstar hydrodynamics code.
