Probing the ubiquity of complex ices in protostars with JWST: the first systematic quantification of weak ice bands between 6.8 and 7.9 micron
Yuan Chen, Ewine F. van Dishoeck, Katerina Slavicinska +18
Complex organic molecules (COMs) are the key to understanding the chemical evolution from simple interstellar molecules to potential prebiotic material. Although COMs have been ext…
JOYS+ analyses of OCN, NO, NO, and complex cyanides in ices -- Thermal processing results in modest enhancement of OCN ice
P. Nazari, N. Brunken, Y. Chen +12
Nitrogen-bearing molecules are more difficult to observe than oxygen-bearing ones, mainly due to the lower abundance of nitrogen in the interstellar medium. Therefore, the formatio…
JOYS: Linking the molecular ice and gas-phase composition towards the high-mass hot core IRAS 18089-1732
C. Gieser, W. R. M. Rocha, Y. Chen +11
Context. The formation and destruction of molecules in the interstellar medium is a complex interplay between gas-phase reactions as well as processes on grain surfaces and within…
JWST Observations of Young protoStars (JOYS): overview of program and early results
E. F. van Dishoeck, Ł. Tychoniec, W. R. M. Rocha +34
The embedded phase is a crucial period in the development of a young star. Mid-IR observations, now possible with JWST with unprecedented sensitivity, spectral resolution and sharp…
JOYS+: link between ice and gas of complex organic molecules. Comparing JWST and ALMA data of two low-mass protostars
Y. Chen, W. R. M. Rocha, E. F. van Dishoeck +16
A rich inventory of complex organic molecules (COMs) has been observed in high abundances in the gas phase toward Class 0 protostars. These molecules are suggested to be formed in…
JWST observations of CO ice: Tracing the chemical environment and thermal history of ices in protostellar envelopes
Nashanty G. C. Brunken, Will R. M. Rocha, Ewine F. van Dishoeck +38
The structure and composition of simple ices can be modified during stellar evolution by protostellar heating. Key to understanding the involved processes are thermal and chemical…
