Best fit massive-star models for the CEMP-no star ET0097 at [Fe/H] = −2. Points with errorbars are 1D LTE abundance measurements from Skúladóttir et al. (2015a). Three models are shown with lines, computed at three different initial rotational velocities, υ_ini/υ_crit = 0 (black), 0.4 (red) and 0.7 (blue). All models are for 25 M_⊙ stars at Z = 10⁻³. The reduced χ² of each fit are shown on the top right, and the residuals of the fits are in the bottom panel.
