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: Launching and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST/MIRI

Łukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +24

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…

HDO ice detected toward an isolated low-mass protostar with JWST

Katerina Slavicinska, Łukasz Tychoniec, María Gabriela Navarro +15

Water is detected in environments representing every stage of star and solar system formation, but its chemical evolution throughout these stages remains poorly constrained. Deuter…
