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…
The Colors of Ices: Measuring ice column density through photometry
Adam Ginsburg, Savannah R. Gramze, Matthew L. N. Ashby +8
Ices imprint strong absorption features in the near- and mid-infrared, but until recently they have been studied almost exclusively with spectroscopy toward small samples of bright…
HETDEX Public Data Release 1: Source Catalog 2 and Data Cubes from ~90 sq deg of Integral-Field Optical Spectroscopy
Erin Mentuch Cooper, Karl Gebhardt, Dustin Davis +36
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is a wide-field, integral-field spectroscopic survey designed to map the large-scale distribution of Lyman-alpha emitting…
CORINOS V: Radiative transfer effects in protostellar ice observations
Will E. Thompson, Jennifer B. Bergner, Neal J. Evans +11
Recent observations of protostars with the James Webb Space Telescope have revealed unprecedented chemical complexity from their ice absorption features. However, these spectra are…
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…
CORINOS IV: Quantifying Baseline-Fitting Uncertainties in SO Ice Measurements with JWST/MIRI
Rachel E. Gross, Yao-Lun Yang, L. Ilsedore Cleeves +15
Sulfur dioxide (SO) ice has been tentatively detected in protostellar envelopes, but its reliability as a solid-state sulfur reservoir remains unclear. We present new measureme…
