Trajectories of dust particles with St = 10⁻⁴ in the planet-induced gas flow (solid lines) and in the unperturbed sub-Keplerian shear flow (dashed lines). We used the result obtained from m03-hw001 to calculate dust trajectories. We set z_s = 0.5 for the orbital calculations. Different colors correspond to different x_s. The filled circles and cross symbols in panel b correspond to x_s and x_e, respectively. The dotted and dashed circles are the Bondi and Hill radii of the planet, respectively. Panel a: x–y plane viewed from the +z direction. Panel b: x–z plane viewed from the −y direction. Panel c: y–z plane viewed from the +x direction. This figure should be compared to Fig. 6a.
