Dust scale height over time for all particle species. The dust scale height is radially averaged from 40 au to 50 au. Each marker represents the averaged dust scale height calculated by taking the rms of the vertical position of the particles for all sizes per orbit. Strong vertical fluctuations are observed for the 1 mm and 500 μm grain sizes after approximately 424 orbits. This corresponds to a regime where the dust distribution is characterized by localized and compact concentrations within vortices (see the orange region in the bottom three panels at three different snapshots).
