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…
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…
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 lumi…
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…
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…
