Disk surface density profile Σ_cyl(r) measured inside a selected cylindrical region (blue). Top two panels: R_ℓ14 and R_40ky_ℓ18 at 103 kyr. Middle: radially accumulated mass of the disk of R_40ky_ℓ18 at 103 kyr. Bottom two panels: R_ℓ14 and R_80ky_ℓ18 at 138kyr. A three-segment power-law fit is overplotted (orange), and the power-law exponentsare shown in the legend. Two vertical dotted lines show the characteristic radii R_kep and R_mag that correspond to the transition of the power-law slope. The masses of the star M_* and of the disk M_d (inside R_kep plus betweenR_kep and R_mag) are also displayed. Most of the disk mass is contained within R_kep.
