When a core-collapse supernova explodes, it ejects elements synthesised during the post-main-sequence evolution of the star, and it produces new elements during the explosion (the so-called explosion nucleosynthesis). In the aftermath of the explosion, a neutron star is left behind. How massive the leftover neutron star is, and how much mass of each element is ejected during the explosion are two of the questions I will address during this talk. One of the biggest uncertainties in predicting both remnant masses and nucleosynthetic yields is the explodability, i.e., which stars explode? Which ones do not and, instead, end up as failed supernovae,. forming a black hole? In this talk, I will present recent results using state-of-the-art 1D simulations that include sophisticated neutrino transport and a mixing-length theory model for neutrino-driven convection, which, as I will show, is a key aspect in the explosion.
