Scatter plot of every tenth particle in four selected size bins of the disk in edge-on orientation for the time step after 150 inner orbits (top) and 600 inner orbits (bottom). The dead-zone outer edge is indicated in the plot. Particles are color-coded according to their size, as in Fig. 2. The black solid line shows the surface density profile of the disk after 150 inner orbits (18 900 yr), the dashed line shows this profile for the disk after 600 inner orbits (75 600 yr).
