Notes. For both low- and intermediate-mass stars (li, progenitors of AGBs) and massive stars (m, progenitors of SNcc and PISNe), the mass ranges depend on the initial metallicity (Zinit) of the stellar population. The upper mass limit of intermediate-mass stars, defined as the minimum mass for the off-centre carbon ignition to occur, is limier for lower metallicity (Umeda & Nomoto 2002; Gil-Pons et al. 2007; Siess 2007). The upper mass limit of massive stars depends on the types of supernovae that are taken into account. Massive stars that explode as core-collapse supernovae (with mup = 40 M⊙ for Z ≠ 0 and an explosion energy of 1044 J) and pair-instability supernovae (with mup = 300 M⊙ and an explosion energy greater than 1044 J) are considered here.
