Carbon-oxygen core mass as a function of the initial masses for all our models in initial mass ranges of 5 − 14 M_⊙ (bottom), and 14 − 50 M_⊙ (top). Colors show the convective core overshooting values. The pink, green, sky-blue, and dark-blue regions show the regions of M_CO where iron core-collapse supernovae, electron capture supernovae, and ONeMg white dwarfs are expected, following Tauris et al. (2015). The blue-shaded region shows the CO core masses of models that could not reach carbon ignition thus CO white dwarfs are assumed to form. The blue and red-edged star symbols indicate the models that produce SN IIb and SN Ib/c. Black-edged hexagonal shapes show models that form BHs.
