If a pronounced density jump is present near the Si/Si-O interface, the star will likely explode. We develop a quantitative criterion by using ∼1300 1D simulations where ν-driven turbulence is included via time-dependent mixing-length theory. This criterion correctly identifies the outcome of the supernova more than 90% of the time. We also find no difference in how this criterion performs on two different sets of progenitors, evolved using two different stellar evolution codes: FRANEC and KEPLER. The explodability as a function of mass of the two sets of progenitors is very different, showing: (i) that uncertainties in the stellar evolution prescriptions influence the predictions of supernova explosions; (ii) the most important properties of the pre-collapse progenitor that influence the explodability are its density and entropy profiles. We highlight the importance that ν-driven turbulence plays in the explosion by comparing our results to previous works.STAMPAenArticle10.3847/1538-4357/acc06a2-s2.0-85160326773https://iopscience.iop.org/article/10.3847/1538-4357/acc06ahttps://api.elsevier.com/content/abstract/scopus_id/85160326773FIS/05 - ASTRONOMIA E ASTROFISICA
