Notes. (a) Non-rotating BPASS V2.0 single-star tracks Eldridge et al. (2008); Eldridge & Stanway (2016), (b) rotating (vrot, i = 40% critical) Geneva tracks, Georgy et al. (2015), (c)rotating (vrot, i = 150 km s−1) FRANEC tracks, Limongi & Chieffi (2018). Values for Z = 0.006 are obtained through linear interpolation between Z = 0.002, 0.014, (d) non-rotating FRANEC tracks Limongi & Chieffi (2018), (e)non-rotating STARS tracks, Dray & Tout (2003), (f)these tracks imply self-stripping already at initial masses of ≈15 M. However, following our strict definition, cannot be smaller than , and hence we set = .
