JWST observations of Sz 65 and Sz 66 reveal higher cold-to-hot water ratios in the secondary disk, attributed to its unstructured dust disk enabling efficient pebble drift across the snow line.
Accretion increases observable water mass in disks by expanding the emitting area via higher central luminosity, while viscous heating has no effect.
