The study of extremely metal-poor (EMP; [Fe/H] < -3.0) and ultra metal-
poor (UMP; [Fe/H] < -4.0) stars is crucial for better understanding
first-star nucleosynthesis and constraining the initial mass function in the early
Universe. However, UMP stars discovered in the past 25
years only number about 25 stars. A few recent theoretical studies have
pointed out that there is likely to exist...

We propose that convective-reactive nucleosynthesis in the dynamic merger of O- and C-shell convection zones can solve the problem of galactic chemical evolution models to account for the observed abundances of odd-Z elements, such as K and Sc. We investigate the convective-reactive events of C-ingestion into O-shell convection for a range of ingestion and
burning parameters through...
