Pre-supernova O-C shell mergers could produce more than the explosion
Joshua Issa, Falk Herwig
The formation of in massive stars is thought to occur during explosive nucleosynthesis, however recent studies have shown it can be produced during O-C shell mer…
Propagating Uncertainties from Nuclear Physics to Gamma-rays in Core Collapse Supernovae
Chris L Fryer, Hendrik Schatz, Samuel Jones +18
Nuclear yields are powerful probes of supernova explosions, their engines and their progenitors. In addition, as we improve our understanding of these explosions, we can use nuclea…
3D Macro Physics and Light Odd-Z Element Production in O-C Shell Mergers: Implications for production and radiogenic heating inventories of rocky exoplanets
Joshua Issa, Falk Herwig, Stephen J. Mojzsis +1
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 promisi…
Impact of 3D macro physics and nuclear physics on the p nuclei in O-C shell mergers
Joshua Issa, Falk Herwig, Pavel Denissenkov +1
O-C shell mergers in massive stars are a site for producing the p nuclei by the process, but 1D stellar models rely on mixing length theory, which does not match the radial ve…
