Comparison of the Be abundances with the theoretical models of Siess et al. (2000). The curves show the Be abundance for stars with solar metallicity at the main sequence as a function of effective temperatures. Four different ages are shown: 10 Myr as a black solid curve, 50 Myr as a red dotted curve, 125 Myr as a green short-dashed curve, and 600 Myr as a blue long-dashed curve. Symbols for the stars are as in Fig. 9.
