CC and PPI+CC models on the Ertl criterion plane for “explodability”. The red area indicates the uncertain boundary region between successful explosions and neutron star formation (white) and collapse with BH formation (gray). The dotted rectangle in the bottom left indicates the range originally showed in Ertl et al. (2016), most of our models require extrapolating outside this range. Blue dots correspond to CC models, while green dots show PPI+CC models.
