Variations of the abundance ratios Ne/He vs. C/He at the surface of WC stars (in number). Models are represented by the lines (the Z = 0.014 are the rotating models of the present paper, the Z = 0.020 is the rotating model of Meynet & Maeder 2003). The points are the observed values by Dessart et al. (2000) (filled circles) and Crowther (2006).
