First quantitative JWST study of weak ice bands in 21 protostars finds CH4 likely dominant at 7.67 um and HCOO- plus other COMs at 7.24/7.40 um, indicating ubiquity of complex ices.

First pixel-by-pixel JWST absorption maps of multiple ice species toward six Class 0 protostars reveal abundance variations from heating and outflows, with total composition matching prestellar formation models covering ~90% of inventory.
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.
Radiative transfer modeling of protostellar ices shows absorption originates mainly from 1000-2000 au at the cavity-envelope transition, with apparent CO2/H2O and CO/H2O ratios potentially underestimated due to line-of-sight effects.
No change detected in ice absorption bands of EC 53 between phases, with ice abundances higher than typical for embedded protostars.
