Size distribution of dust grains (left) and average eccentricity of different-sized dust grains (right) in the Reference, Fomalhaut, and Zodi runs at three selected stellocentric distances: 100 au (solid lines), 150 au (dashed), and 200 au (dotted). Note that only dust grains smaller than 10 µm are shown. In both panels, the blowout grain size is marked with a vertical black line.
