Comparison of the models (blue diamonds), (red diamonds), (brown diamonds), and (magenta diamonds) with observations of surface Li and Be in the Hyades (filled squares) and Praesepe (open squares) open clusters. Downward triangles are for Li upper limits. Stars corresponding to the Li dip (6400 K < T_eff < 6800) are represented in dark grey and stars outside of the Li dip are represented in light grey. Observations are directly extracted from Boesgaard et al. (2004b, 2016) without any modification (no NLTE correction for Li abundances). The dark grey dashed line represents the linear correlations found by Boesgaard et al. (2020) with A(Be) = 0.43 × A(Li)−0.17 for stars in the cold edge of the Li dip.
