Accretion increases observable water mass in disks by expanding the emitting area via higher central luminosity, while viscous heating has no effect.
Updated DALI models reproduce observed C2H2 fluxes with solar C/O and find the C2H2/H2O flux ratio sensitive to elemental abundances and small-grain abundance in planet-forming disk regions.
