A portable expression is derived to estimate water ice crystallinity from Fresnel peak strength in scattered-light spectra at ~90° angles, yielding 10-20% for the HD 181327 debris disk and ~50% for the d216-0939 protoplanetary disk.

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.
