Dust distribution in Model 2. From left to right, the dust particle distributions in the (r, φ) plane for 200 μm, 3.2 mm, and 1.3 cm dust sizes in Model 2, respectively. The black lines show radial density distribution of the gas normalized between (0, 2 π), while the filled green circles mark the position of the planets. The plots are zoomed in the inner region (0.5, 5) au and the width of the density profile is multiplied by a constant for readability.
