Modeling the formation of a 13C pocket in AGB stars with convective boundary mixing

Project summary
The mechanism of proton ingestion from the bottom of the convective envelope into the He- and C-rich shell in low-mass AGB stars, that is needed to trigger the s-process nucleosynthesis under radiative conditions, is not known yet. One of the proposed mechanisms is mixing by internal gravity waves. It is modelled in this project by adjusting parameters of convective boundary mixing.
About the simulation codes
We used the MESA stellar evolution and NuGrid post-processing nucleosynthesis codes.
