Comparison of dust fluxes and the fraction of total accreted dust mass in the toy model with and without planet. Top: comparison of the dust flux in the inner disk (at 2 AU) and outer disk (at 15 AU) in the toy model with a Saturn-mass planet at 5 AU (panel B in Fig. 1) and a model without a planet (panel C in Fig. 1). The two green 15 AU lines overlap. Bottom: total dust mass accreted through the inner disk over time in the model with (solid line) and without (dashed line) a planet.
