Results from dust evolution models for the PDS 70 disk. Specifically, dust density distributions after 1 Myr (top panels) and 10 Myr (bottom panels) of evolution as a function of grain size (y-axis) and distance from the star (x-axis). The difference in simulations is the minimum grain size in the initial dust size distribution, that is, decreasing from the left to the right column. The y-axis is different for each column because the grain size grid depends on the initial grain size that is assumed (given in the title of each column).
