Lithium (left) and beryllium (right) depletion versus effective temperature for four different masses M  =  0.8 M_⊙ (red symbols), 0.9 M_⊙ (green symbols), 1 M_⊙ (blue symbols), 1.1 M_⊙ (yellow symbols) at three different ages t = 1.7 Gyr (crosses), 4.6 Gyr (dots), 6 Gyr (squares). For each mass, at a given age, the results of the six models corresponding to different rotational histories are displayed (see text). Initial abundances are shown as horizontal long-dashed lines, lithium abundances below −1 are plotted at −1. The four dashed lines correspond to models A of Pinsonneault et al. (1990). The dotted curve corresponds to model C3 of Pinsonneault et al. (1990), which predicts the highest Be depletion.
