Observations of the HK Tau binary with JWST reveal gas-phase molecular lines in the low-inclination primary and ice absorption features in the edge-on secondary, enabled by their differing inclinations.
JWST observations of Sz 65 and Sz 66 reveal higher cold-to-hot water ratios in the secondary disk, attributed to its unstructured dust disk enabling efficient pebble drift across the snow line.
The paper reviews techniques for measuring protostellar accretion, analyzes methodological differences and caveats in comparing observations with simulations, and outlines next steps for a fuller picture.
