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…
IPA: Class 0 Protostars Viewed in CO Emission Using JWST
Adam E. Rubinstein, Neal J. Evans, Himanshu Tyagi +24
We investigate the bright CO fundamental emission in the central regions of five protostars in their primary mass assembly phase using new observations from JWST's Near-Infrared Sp…
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…
Discovery of a collimated jet from the low luminosity protostar IRAS 162532429 in a quiescent accretion phase with the JWST
Mayank Narang, Manoj P., Himanshu Tyagi +36
Investigating Protostellar Accretion (IPA) is a JWST Cycle~1 GO program that uses NIRSpec IFU and MIRI MRS to obtain 2.9--28~m spectral cubes of young, deeply embedded protostar…
Investigating Protostellar Accretion-Driven Outflows Across the Mass Spectrum: JWST NIRSpec IFU 3-5~m Spectral Mapping of Five Young Protostars
Samuel Federman, S. Thomas Megeath, Adam E. Rubinstein +35
Investigating Protostellar Accretion is a Cycle 1 JWST program using the NIRSpec+MIRI integral field units to obtain 2.9--28 m spectral cubes of five young protostars with lumin…
JOYS: Disentangling the warm and cold material in the high-mass IRAS 23385+6053 cluster
C. Gieser, H. Beuther, E. F. van Dishoeck +20
(abridged) We study and compare the warm (>100 K) and cold (<100 K) material toward the high-mass star-forming region IRAS 23385+6053 (IRAS 23385 hereafter) combining high angular…
JOYS: JWST Observations of Young protoStars: Outflows and accretion in the high-mass star-forming region IRAS23385+605
H. Beuther, E. F. van Dishoeck, L. Tychoniec +21
Aims: The JWST program JOYS (JWST Observations of Young protoStars) aims at characterizing the physical and chemical properties of young high- and low-mass star-forming regions, in…
