(1) Non-rotating models from Meynet et al. (1994) used to estimate the minimum initial mass of stars ending their lifetime in the WNL phase at that metallicity. These models were computed with artificially enhanced mass loss rates, which somewhat compensates for the neglect of the effects of rotation. (2) Model computed up to the end of silicon burning.

Note: All masses are given in $[{M}_\odot]$. The SN type is given for $m^{\rm min}_{\rm H}=0$, $m^{\rm min}_{\rm He}=0.6$ and supposing that a SN occurs even when a BH is formed (see text). The remnant masses used are those given by Hirschi et al. (2005), except for the homogenous models (see text).
