Production of heavy -elements and Ti in Cas A: comparison to abundances from 1D core-collapse supernova models and evidence for Carbon-Oxygen shell mergers
Luca Boccioli, Lorenzo Roberti, Chris L Fryer +3
The merger between the carbon (C) and oxygen (O) shells hours to days before the collapse of a massive star significantly changes its nucleosynthesis, which is reflected in the ele…
Explodability matters: how realistic neutrino-driven explosions change explosive nucleosynthesis yields
Luca Boccioli, Lorenzo Roberti
Explosive nucleosynthesis is affected by many uncertainties, particularly regarding assumptions and prescriptions adopted during the evolution of the star. Moreover, simple explosi…
Explosion mechanism of core-collapse supernovae: role of the Si/O interface
Luca Boccioli, Lorenzo Roberti, Marco Limongi +2
We present a simple criterion to predict the explodability of massive stars based on the density and entropy profiles before collapse. If a pronounced density jump is present near…
