Be (top) and Li (bottom) abundances vs. age. For the models of Be depletion, we adopt an initial meteoritic A(Be) = 1.45 dex, which is based on the value by Lodders (2003; 1.41 dex), plus the 0.04 dex gravitational settling effect over 4.5 Gyr. The models of Li depletion were normalized to the solar Li abundance. The green solid lines are the models by Pinsonneault et al. (1989), the red dotted lines represent the models by do Nascimento et al. (2009), the blue dashed lines are the modified models of do Nascimento et al. (2009; see text), and the purple long-dashed lines are predictions of Be depletion by Xiong & Deng (2007) and Li depletion by Xiong & Deng (2009). The teal dotted-dashed line (top panel) is the same Be depletion model of do Nascimento et al. (2009) shown by the red dotted lines, but with a higher initial A(Be) = 1.50 dex (rather than A(Be) = 1.45 dex). The additional 0.05 dex is to compensate for the refractory depletion of Be in the Sun (see text).
