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.
Halos in Elias 2-24, IM Lup, and DM Tau hold 20-30% of total dust mass with cm-sized grains, helping resolve the disk mass-budget problem even though drift and growth timescales are shorter than disk ages.
Numerical simulations of porous fractal and consolidated particles show stronger forward scattering, broader polarization peaks, and lower absorption per unit mass than compact spheres, implying larger dust masses from observed fluxes.
