Synthetic ALMA observations at 1.3 mm of the structured disk model at 1.3 Myr, 1.6 Myr, and 1.8 Myr, generated using the SIMIO package (Kurtovic et al., in prep.) to post-process our radiative transfer model. The image shows how our disk would look if it was observed with the same ALMA configuration of Elias24 (Huang et al. 2018, from the DSHARP sample), assuming a distance of 139 pc and an inclination of 29°. The beam size is plotted in the lower-left corner. The orbit of the primordial gap (r_gap = 40 AU) is marked with a dashed line. We note that this is not intended to be a comparison “with” Elias24.
