Notes. vdHG97: van den Hoek & Groenewegen (1997); WW95: Woosley & Weaver (1995); M92: Maeder (1992); K06: Kobayashi et al. (2006); M01: Marigo (2001); KL07: Karakas & Lattanzio (2007); K10: Karakas (2010). The models adopting the yields by Marigo (2001) for LIMSs use self-consistent nucleosynthesis prescriptions from Portinari et al. (1998) for stars of initial mass m = 6 M⊙ and m = 7 M⊙.
