Wind-momentum – luminosity relation for O and WNh stars in 30 Dor. Different symbols indicate empirical results for the most massive stars in 30 Dor from Bestenlehner et al. (2014) in blue, O-type giants and supergiants from Ramírez-Agudelo et al. (2017) Tables C.4 (dark green) and C.5 (light green), and O-type dwarfs from Sabín-Sanjulián et al. (2017) Tables A.1 (red) and A.2 (pink). Upper limits are indicated in grey. Evolutionary tracks are indicated by coloured lines analogous to Fig. 5 but restricted to the O star range. Predicted absolute numbers of stars according to our population synthesis models are mapped and colour coded as indicated by the colour bar on the right.
