Surface densities of gas (red solid lines), small dust (blue dashed lines), and grown dust (black solid lines) taken along the azimuthal cuts at different distances from the star: r = 20 AU, r = 50 AU, r = 82 AU, and r = 150 AU. The dashed pink and solid cyan lines show the gas pressure (in the code units) and the maximum radius of dust grains a_r (in cm) taken along the same cuts. The evolution time is t = 0.2 Myr. We applied different scaling factors for the small dust density, grown dust density, and maximum dust radius.
