HR diagram with the position of the sample WN stars shown by triangles (for LMC targets) and squares (Galactic targets). Circles correspond to the comparison Galactic WN4 stars. On the left panel, the evolutionary tracks are from Meynet & Maeder (2005), while on the right panel they are from Ekström et al. (2012). The bold part of the tracks corresponds to a hydrogen mass fraction higher than 0.1.
