Dust density distribution at 1 Myr of evolution when two planets are interacting with a disk at 5 AU (1 M_Jup) and at 17.5 AU (5 M_Jup) with α_turb = 10^-2 (top), v_f = 10 m s^-1 (left) and α_turb = 10^-3 (bottom), v_f = 30 m s^-1 (right). The solid line corresponds to the particle size for which particles experience the highest radial drift, which is directly proportional to Σ_g (Eq. (1)).
