Accretion window with the different Stokes numbers in the UP-m001-hw003 (top) and the PI-Stokes-m001-hw003 cases (bottom). We assume α = 10⁻³ and the dust-to-gas ratio equal to 10⁻². Color represents the density of the pebbles expressed by Eq. (18) normalized by the gas density. The vertical dashed lines correspond to the corotation radius for pebbles (Eq. (10)). The two panels in panelsa and e show the enlarged outlines of accretion windows. We note that the color contour is saturated for ρ_p ≲ 10⁻³.
