The curves μ2M = CEDD for 3 values of CEDD. The location of the ZAMS, He-stars and CO-cores are indicated. The average point for 30 WN stars without hydrogen studied by Hamann et al. (2006) is shown, with indications of the limits within they are observed. From the study by Sander et al. (2011), we show the averages for 4 transition WN/WC stars, for 39 WC stars (with indications of the limits) and for 2 WO stars.
