Extended Data Fig. 7: Advanced evolution of the custom GENEC models calculated with our adapted wind mass-loss scheme.
From: Discovery of a transitional type of evolved massive star with a hard ionizing flux
Effective temperature (without wind correction, upper panel), mass (middle panel) and mass-loss rate (lower panel) as a function of age, focusing on the time beyond central hydrogen burning. Similar to the HRD plot in Fig. 4, the surface composition is indicated by the track color and dots mark steps of 50 kyr. For comparison, the derived the effective temperatures, masses, and mass-loss rates of the three WN2 stars and M33WR 206 are indicated as dashed light blue horizontal lines.
