Empirical correlations of gas-disk mass with gas-disk radius (left) and stellar mass (right) at 5 Myr. The blue marks values derived from simulations, and the black shows the values of ten targets in AGE-PRO. The red line is fit using a MCMC method, and the 1σ credible interval is marked in light red. Disks with substructures identified in AGE-PRO (Vioque et al. 2025) are shown in yellow, and those with MHD winds traced by the [O I] λ 6300 line (Fang et al. 2023) are highlighted in bright purple.
