Evolution of the surface [Fe/H] in dex (top panel), helium YSurf in mass fraction (middle panel), and the surface [C/H] in dex (lower panel) as a function of νmax for different masses and initial rotation speeds for models including atomic diffusion with radiative acceleration. Horizontal dotted lines represent the initial abundance. The models are A1, B1, B2, C1, and C2 from Table 1.
