Fig. 12


Same as Fig. 8 but focusing on the upper part of the HR diagram. The orange squares correspond to WNh stars. We have used stars for which stellar parameters determined from spectroscopic analysis are available. In the upper (lower) panels the Geneva (FRANEC) models are shown. The tracks have been plotted for X(He) < 0.75 which corresponds to He/H ~ 0.8 by number. Left: tracks with rotation. Right: non rotating tracks.

This figure is made of several images, please see below:
