Trajectories of pebbles with St = 10⁻⁴ in UP-m003-hw01 case (top) and PI-Stokes-m003-hw01 case (bottom). The height of the initial position of the pebbles is z_s = 0.03 [H]. The red and blue solid lines correspond to the trajectories of pebbles which accreted and did not accrete onto the planet, respectively. The black dots at the center of each panel denote the position of the planet. The sphere around the planet represents the Bondi radius of the planet. We only plot the trajectories within the region where r < 2R_Hill. The interval of pebbles at their initial locations is 0.01 [H].
