Formation of carbonyl sulfide (OCS) via SH radicals in interstellar CO-rich ice under dense cloud conditions
Julia C. Santos, Harold Linnartz, Ko-Ju Chuang
Carbonyl sulfide (OCS) is widely observed in the gas phase towards star-forming regions and was the first of the only two sulfur-bearing species detected in interstellar ices so fa…
Formation of S-bearing complex organic molecules in interstellar clouds via ice reactions with C2H2, HS, and atomic H
Julia C. Santos, Joan Enrique-Romero, Thanja Lamberts +2
The chemical network governing interstellar sulfur has been the topic of unrelenting discussion for the past decades due to the conspicuous discrepancy between its expected and obs…
JWST Observations of Young protoStars (JOYS): Linked accretion and ejection in a Class I protobinary system
Åukasz Tychoniec, Martijn L. van Gelder, Ewine F. van Dishoeck +19
Accretion and ejection sets the outcome of the star and planet formation process. The mid-infrared wavelength range offers key tracers of those processes that were difficult to det…
JWST detections of amorphous and crystalline HDO ice toward massive protostars
Katerina Slavicinska, Ewine F. van Dishoeck, Åukasz Tychoniec +19
This work aims to utilize the increased sensitivity and resolution of the JWST to quantify the HDO/HO ratio in ices toward young stellar objects (YSOs) and to determine if th…
