IPA: Morphology and Kinematics of Molecular Hydrogen Winds in Five Young Protostars across the Mass Spectrum Observed with JWST
Himanshu Tyagi, P. Manoj, Mayank Narang +29
Molecular winds may play a key role in governing angular momentum transport and accretion during the early evolution of protostars. We present the morphology and kinematic properti…
JOYS: Launch and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST MIRI
Łukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +25
Protostellar winds can theoretically lift solids from the planet-forming disks, but direct evidence for launched dust has been scarce so far. Numerous atomic lines that are unique…
Investigating the Nested Structure of the Outflow from the Low Luminosity Protostar IRAS 16253-2429 using JWST and ALMA
Mayank Narang, Himanshu Tyagi, Nagayoshi Ohashi +37
Understanding the earliest stage of star and planet formation requires detailed observations to address the connection and interplay between the accretion, outflow and disk evoluti…
The Structure and Kinematics of Three Class 0 Protostellar Jets from JWST
Samuel A. Federman, S. Thomas Megeath, Alessio Caratti o Garatti +20
We present observations of jets within 2000 au of three deeply embedded protostars using 2.9-27 micron observations with JWST. These observations show the morphologies and kinemati…
IPA. Accretion rate of a low-mass Class 0 protostar, measured via mid-infrared fluorescent OH emission
Dan M. Watson, Mayank Narang, Caeley V. Pittman +41
The earliest stages of star formation are highlighted by complex interactions between accretion, outflow, and radiative processes, which shape the chemical and physical environment…
CORINOS. III. Outflow Shocked Regions of the Low-mass Protostellar Source IRAS 15398-3359 with JWST and ALMA
Yuki Okoda, Yao-Lun Yang, Neal J. Evans +10
While molecular outflows have been studied in details with radio interferometry, observations of the hotter gas in protostellar outflows at a comparable physical scale is often cha…
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 detections of amorphous and crystalline HDO ice toward massive protostars
Katerina Slavicinska, Ewine F. van Dishoeck, Łukasz 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…
