DustPy outputs at 1 Myr for the compact (left panel) and the extended disk models (right panel). Top panel: grain size distribution of the dust particles as a function of the radial distance from the star. At each radius, the maximum grain size, is highlighted in lime green. Bottom panel: radial profiles of gas (in blue) and dust (in orange) total column densities. The vertical gray lines represent the position of the bright (B) and dark (D) gaps in the dust surface density profile.
