Fig. 20


Abundance profiles in our diffusion model (, log g = 7.60). Short-dashed (blue) lines: unrealistically high abundance of the generic iron-group element (IG, see text), thick (red) lines: reduced IG abundance, horizontal long-dashed, thin (cyan) lines: the abundances in our final homogeneous model. In the O panel, the thick dashed (green) line shows our modified O-abundance profile (see text).
