3D Macro Physics and Light Odd-Z Element Production in O-C Shell Mergers: Implications for 40K Production and Radiogenic Heating Inventories of Rocky Exoplanets

The light odd- Z elements P, Cl, K, and Sc are underproduced in galactic chemical evolution models compared to spectroscopic observations of stars in the Milky Way. The most promising solution to this puzzle is that some massive stars experience O-C shell mergers, boosting their yields through dynam...
