Ejected metal mass fraction, m Z /m, as a function of the initial stellar mass, m. The data of AGB stars (1–8M⊙) are taken from Karakas (2010) and those of SNe (8–40M⊙) are taken from Nomoto et al. (2006). The meaning of the symbols are the same as in Fig. 1. The solid line is a fitting function given by Eq. (20). The dotted lines are the cases a factor of two higher or lower than the solid line.
