Trajectories of pebbles in the PI-Stokes case with St = 10⁻² at the midplane around the embedded planets with m = 0.03 (left panel) and 0.3 (right panel). We set z_s = 0. The red and blue solid lines correspond to the trajectories of pebbles which accreted and did not accrete onto the planet, respectively. The dashed and dotted circles show the Hill and the Bondi radius of the planet, respectively. The sizes of the Hill radius are 0.22 [H] for m = 0.03 and 0.46 [H] for m = 0.3. The black dots at the center of each panel denote the position of the planet. The interval of pebbles at their initial locations is 0.05 [H].
