Same as Fig. 8, but for Be. Boxes are for Be observations of solar-mass stars in different open clusters and are colour-coded according to their metallicity, as in Fig. 1. The numbers I–V identify the clusters: (I) IC 2602 and IC 2391 (Smiljanic et al. 2011), (II) Pleiades (Boesgaard et al. 2003a), (III) Ursa Major (Boesgaard et al. 2003b), (IV) Coma Ber (Boesgaard et al. 2003b), and (V) Hyades (Boesgaard et al. 2004). The solar beryllium with uncertainties comes from Asplund et al. (2009, photospheric value). The orange dots refer to the four profiles extracted from the star evolution shown in Fig. 7.
