Fig. 8.


Same as Fig. 7 with OB and Wolf–Rayet stars from comparison clusters in gray: the Quintuplet (top; Liermann et al. 2012; Clark et al. 2018); the galactic center cluster (middle; Martins et al. 2007); cluster [DBS2003]-179 (bottom; Borissova et al. 2012). For clarity only the 25 and 40 M tracks are plotted, as well as only the 5 and 6 Myr isochrones. Error bars have also been dropped. No distinction of luminosity class is made for OB stars.
