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.

Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
