This work focuses on the ice features toward the binary protostellar system Ced 110 IRS 4A and 4B, and observed with JWST as part of the Early Release Science Ice Age collaboration…
Infrared Spectra of Solid-State Ethanolamine: Laboratory Data in Support of JWST Observations
T. Suhasaria, S. M. Wee, R. Basalgète +4
Ethanolamine (NHCHCHOH, EA) has been identified in the gas phase of the ISM within molecular clouds. Although EA has not been directly observed in the molecular ice pha…
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…
A JWST/MIRI analysis of the ice distribution and PAH emission in the protoplanetary disk HH 48 NE
J. A. Sturm, M. K. McClure, D. Harsono +18
Ice-coated dust grains provide the main reservoir of volatiles that play an important role in planet formation processes and may become incorporated into planetary atmospheres. How…
JOYS: MIRI/MRS spectroscopy of gas-phase molecules from the high-mass star-forming region IRAS 23385+6053
L. Francis, M. L. van Gelder, E. F. van Dishoeck +16
Space-based mid-IR spectroscopy provides tracers of warm gas in star-forming regions that are inaccessible from the ground. Past mid-IR spectra of bright high-mass protostars in th…
JWST Observations of Young protoStars (JOYS+): Detection of icy complex organic molecules and ions. I. CH, SO, HCOO, OCN, HCO, HCOOH, CHCHOH, CHCHO, CHOCHO, CHCOOH
W. R. M. Rocha, E. F. van Dishoeck, M. E. Ressler +23
Complex organic molecules (COMs) detected in the gas phase are thought to be mostly formed on icy grains, but no unambiguous detection of icy COMs larger than CH3OH has been report…
JOYS+: mid-infrared detection of gas-phase SO emission in a low-mass protostar. The case of NGC 1333 IRAS2A: hot core or accretion shock?
M. L. van Gelder, M. E. Ressler, E. F. van Dishoeck +18
JWST/MIRI has sharpened our infrared eyes toward the star formation process. This paper presents the first mid-infrared detection of gaseous SO emission in an embedded low-mass…
JOYS: Disentangling the warm and cold material in the high-mass IRAS 23385+6053 cluster
