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…
JWST/MIRI Detection of Molecular H Winds from an Edge-on Class II Source HV Tau C
Vinod Chandra Pathak, P. Manoj, Himanshu Tyagi +14
The paper uses JWST/MIRI mid‑infrared spectroscopy to detect and characterize a wide‑angled molecular hydrogen wind from the edge‑on Class II protoplanetary disk HV Tau C, measurin…
Probing the ubiquity of complex ices in protostars with JWST: the first systematic quantification of weak ice bands between 6.8 and 7.9 micron
Yuan Chen, Ewine F. van Dishoeck, Katerina Slavicinska +18
Complex organic molecules (COMs) are the key to understanding the chemical evolution from simple interstellar molecules to potential prebiotic material. Although COMs have been ext…
MINDS: Complementary inclinations in the binary system HK Tau reveal gas- and ice-phase chemistry
Alice Somigliana, Giulia Perotti, Nicolás T. Kurtovic +18
[Abridged] HK Tau is a roughly equal mass pre-main sequence binary system consisting of a low-inclination primary (57 deg) and an edge-on (83 deg) secondary. We present JWST/MIRI o…
MINDS survey of silicates in T Tauri disks: Correlation between dust and gas
J. Varga, Th. Henning, L. B. F. M. Waters +20
Context. Silicates are key constituents of planet-forming disks and major building blocks of rocky planets. Mid-infrared spectral features of micron-sized silicate grains trace gra…
The asymmetric carbon-rich chemistry of the planet-forming disk of HD 142527 triggered by late infall
Milou Temmink, Ewine F. van Dishoeck, Alice S. Booth +3
The planet-forming disk of HD 142527 is known for its azimuthally asymmetric dust trap, shadows, and spiral arms. We use new ALMA observations to investigate the molecular composit…
