Positions of the R136 sources (optical + UV analysis, dark blue points) in the Hertzsprung-Russell diagram. Yellow dashed and dotted yellow lines are LMC evolutionary tracks of Brott et al. (2011a) and Köhler et al. (2015), respectively. Red solid lines are isochrones. All tracks have an initial rotation of ≈160 km s⁻¹, representative for the O-stars in the sample. We note that the tracks shown in Fig. 17 have a higher initial rotation.
