Protoplanetary disk images (top row) and scattered-/transmitted-light spectra (bottom-left and bottom-middle) obtained from the radiative-transfer simulations, together with the crystallinity dependence of their Fresnel-feature heights (bottom-right). For the edge-on case, the Fresnel-feature height is measured in absolute value of feature depth.

Constraints On The Crystallinity Of Water Ice In Planet-forming Disks From Infrared Scattered-Light Spectra

by Keith CowingMay 23, 2026May 23, 2026

The crystallinity of water ice not only records the thermal history experienced by an astronomical body, but also affects the composition of forming planets by controlling the trapping of volatile […]
