Abundance of Be (divided by the initial abundance Be₀) versus time (in yr) in stars that have undergone a given number N_burst of accretion bursts with Ṁ = 5  ×  10^-4   M_⊙   yr^-1 and duration Δt_burst = 100 yr. The blue solid line corresponds to an accreting sequence with final mass 1 M_⊙ with N_burst = 20 bursts. The red dashed line corresponds to a final mass 0.8 M_⊙ with N_burst = 16. The accretion process starts from an initial seed mass of 10 M_J (see Baraffe & Chabrier 2010, for details). The black dotted line indicates the Be abundance for non-accreting models of 0.8 M_⊙ or 1 M_⊙, which are the same for both masses since Be is not depleted in those models.
