Azimuthally averaged radial distributions of the grown dust (red lines) and small dust (blue lines) surface densities, total dust to gas ratio (green lines), maximum radius of dust grains (thin black solid lines), ratio of grown to total dust surface densities (dashed black lines), and fragmentation barrier afrag (thick black solid lines) vs. radial distance from the center of the clump. The evolutionary time and the radial distance of the clump from the star Rcl are indicated in each panel. The horizontal dotted lines mark the canonical dust-to-gas ratio of 1:100 for convenience.
