Three-dimensional distributions of dust, for the model represented in Figure 11, displayed at a binary phase around apocenter passage (left) and pericenter passage (right). The positions of the dust are projected in the r-θ plane in the top panels (θ_s = 0 at the disk mid-plane) and r-ϕ plane. Dust of different sizes are rendered by different colors, as indicated in the legend. The filled gray circles represent the position of the planet.
