Left panel: Hydrogen mass fraction at the stellar surface as a function of the stellar luminosity from the H-core ignition to the C-core depletion. Right panel: Hydrogen mass fraction at the stellar surface as a function of the stellar temperature from He ignition to the C-core depletion. The grey stars and triangles represent the observational values calculated by Martins et al. (2007) for Ofpe/WN9 and WN stars, respectively. The solid and dashed lines represent new and old models, respectively, as in Fig. 1.
