JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS370 -- Evidence for an Opacity Hole and Thermal Processing of Ices
Himanshu Tyagi, Manoj P., Mayank Narang +35
The composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during th…
A Natural Laboratory for Astrochemistry, a Variable Protostar B335
Jeong-Eun Lee, Neal J. Evans, Giseon Baek +3
Emission lines from complex organic molecules in B335 were observed in four epochs, spanning a luminosity burst of about 10 years duration. The emission lines increased dramaticall…
ALMASOP. The Localized and Chemically rich Features near the Bases of the Protostellar Jet in HOPS 87
Shih-Ying Hsu, Chin-Fei Lee, Sheng-Yuan Liu +24
HOPS 87 is a Class 0 protostellar core known to harbor an extremely young bipolar outflow and a hot corino. We report the discovery of localized, chemically rich regions near the b…
CORINOS II. JWST-MIRI detection of warm molecular gas from an embedded, disk-bearing protostar
Colette Salyk, Yao-Lun Yang, Klaus M. Pontoppidan +8
We present James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI) observations of warm CO and HO gas in emission toward the low-mass protostar IRAS 15398-3359, observ…
JWST/MIRI detection of suprathermal OH rotational emissions: probing the dissociation of the water by Lyman alpha photons near the protostar HOPS 370
David A. Neufeld, P. Manoj, Himanshu Tyagi +22
Using the MIRI/MRS spectrometer on JWST, we have detected pure rotational, suprathermal OH emissions from the vicinity of the intermediate-mass protostar HOPS 370 (OMC2/FIR3). Thes…
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…
Hunt for complex cyanides in protostellar ices with JWST: Tentative detection of CHCN and CHCN
P. Nazari, W. R. M. Rocha, A. E. Rubinstein +20
Nitrogen-bearing complex organic molecules have been commonly detected in the gas phase but not yet in interstellar ices. This has led to the long-standing question of whether thes…
