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…
A Chemical Inventory of the Disk around the Class 0 Protostar L1527 IRS with ALMA
Merel L. R. van 't Hoff, Łukasz Tychoniec, John J. Tobin +1
Planet formation starts in disks that are still embedded within their natal envelopes. Here, we compile an extensive inventory of the chemical composition of the disk and envelope…
Subarcsecond Multi-line Observations of NH with VLA toward the Class 0 Source IRAS 16293-2422
Yoshihide Yamato, Yuri Aikawa, Kenji Furuya +2
Ammonia (NH) is one of the key volatiles that plays a central role in nitrogen chemistry and its evolution during the epoch of star and planet formation. We present subarcsecon…
Radio Continuum and Water Maser Monitoring of the Outburst in HOPS 373: Free-Free Emission Does Not Respond to the Outburst
John Tobin, Doug Johnstone, Greg Herczeg +5
We present VLA C-band (5~cm) continuum, K-band (1.3~cm) continuum, and water maser (22.235 GHz) monitoring of the protostar HOPS-373. We additionally present the contemporaneous mo…
JOYS: A JWST/MIRI survey of the evolution of H winds and jets from low-mass protostars
L. Francis, Å. Tychoniec, E. F. van Dishoeck +20
Protostellar outflows display wide-angle winds and collimated jets, the magnetocentrifugal launching of which enables accretion onto the protostar. The majority of the outflow mass…
Water D/H in 3I/ATLAS as a Probe of Formation Conditions in Another Planetary System
Luis E. Salazar Manzano, Teresa Paneque-Carreño, Martin A. Cordiner +17
Water reservoirs in the Solar System exhibit a deuterium enrichment that links back to the physical environment at the time of stellar birth. Gas-phase and ice-grain deuterium enri…
