DALI modeling with updated warm chemistry finds C2H2/H2O IR flux ratio in T Tauri disks is sensitive to C/O, total O/H, and small-grain abundance, with JWST data suggesting sub-unity C/O and common enhanced O/H.
Accretion increases observable water mass in disks by expanding the emitting area via higher central luminosity, while viscous heating has no effect.
