Dust density distribution after 1.5 Myr of evolution and real part of the visibilities at 870 μm at different times of dust evolution, when a single planet interacts with the disk for two different values of disk viscosity, α = 2 × 10^-3 (left column) and α = 5 × 10^-3 (right column). From top to bottom, the masses of the planet are: 1, 5, and 10 M_Jup. ALMA Cycle 0 data are over-plotted in Fig. 3. In the dust density distribution plots, the white and blue lines correspond to St = 1 (Eq. (3)), and a_frag (Eq. (9)) respectively.
