Logarithm of the vertical dust-to-gas ratio ${\rho }_{\mathrm{d}}^{\text{large}}/{\rho }_{\mathrm{g}}$ in the vicinity of the planet at t=375 orbits (same t as in Fig. 9). The streamlines of the gas and dust meridional flows (white and red arrows, respectively) are overlaid. The Hill radius is marked with a dotted black circle. The formation of two plumes associated with polar outflows is apparent; nevertheless, the dust fraction contained in the plumes is small.
