Selected re-emission maps for the disk after 150 inner orbits (18 900 yr, left column) and 600 (75 600 yr, right column). Each wavelength (441 μm, 871 μm, 1.3 mm and 2.0 mm) is presented in its own line. The square root of thermal re-emission flux per arcsec² is shown color-coded. At both time steps and for every wavelength a gap is visible in the maps. Depending on time and wavelength, the re-emission maps of the disk show different structures (rings and concentrations).
