Fig. 11
Observed lithium abundances (coloured symbols as in Fig. 4), compared to stellar evolution model predictions for two different efficiencies of AddMix (see text). The initial abundance of the models (horizontal dashed line and shaded region), log ε(Li) = 2.53 ± 0.10, compares well to the predicted primordial lithium abundance (dotted horizontal line and shaded region), log ε(Li) = 2.69 ± 0.04.
