Mass fraction in planetesimals (top panels), pebbles (middle panels) and dust (bottom panels) vs. trap efficiency ɛ (left panels) and disk mass μ = M_disk∕M_⊙ (right panels). Left panels: the disk mass is fixed at μ = 0.02 while the trap efficiency is fixed to ɛ = 0.01 in the right panels. Colors correspond to different times in the disk evolution. Data is taken from the same simulation runs that were depicted in Fig. 6. However, Fig. 7 does not differentiate between primordial and collisional populations and depicts their sum.
