Chemical Demographics of Star-forming Regions
Maria N. Drozdovskaya, Timea Csengeri, Maria Teresa Beltrán +35
Our understanding of complex organic chemistry during the formation of stars and planets is shaped by a handful of cherry-picked sources with bright molecular emission lines. This…
An Eccentric Massive Protobinary Assembled via a Core-merger Parabolic Encounter
Yao Wang, Yichen Zhang, Rubén Fedriani +14
Most massive stars form in binary systems, which profoundly influence their subsequent evolution. However, how such systems form remains poorly understood, with several competing s…
JWST Edge-on Disk Ice (JEDIce): Vibrationally hot, rotationally cold H in the outer disk of Oph 163131 non-thermally excited by UV and cosmic rays
Korash Assani, Zhi-Yun Li, Jennifer B. Bergner +19
Constraining ionization and excitation processes in protoplanetary disks is essential for understanding the chemical structure and evolution of disk material, shaping planet format…
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…
EPISODE II: Variability in the CO and HO rovibrational absorption lines in a periodically variable protostar EC 53
Seokho Lee, Jeong-Eun Lee, Chul-Hwan Kim +19
We present two-epoch JWST NIRSpec and MIRI observations of the young protostar EC 53 (V371 Ser), a periodically variable source with well-characterized quiescent and burst phases.…
Measuring metal sulfides in interstellar dust with PRIMA
Izaskun Jiménez-Serra, Shaoshan Zeng, Yao-Lun Yang +5
Sulfur is known to undergo severe depletion when moving from diffuse clouds to the denser regimes of the interstellar medium in molecular clouds. The form in which sulfur gets depl…
The SOMA Atomic Outflow Survey. I. An Atomic OI and Highly Ionized OIII Outflow from Massive Protostar G11.94-00.62
Phillip Oakey, Yao-Lun Yang, Jonathan C. Tan +7
Massive stars regulate galaxy evolution and star formation through their physical and chemical feedback, but their formation remains poorly understood. Accretion-powered outflows p…
Image Profile (IMPRO) Fitting of Massive Protostars. I. Method Development and Test Cases of Cepheus A and G35.20-0.74N
Yao-Lun Yang, Jonathan C. Tan, Rubén Fedriani +1
Massive stars play a critical role in the evolution of galaxies, but their formation remains poorly understood. One challenge is accurate measurement of the physical properties of…
PEACHES IV: Tracing the Formation & Evolution of CH in Perseus Low-Mass Protostars
Jack G. Anderson, Jennifer B. Bergner, Yao-Lun Yang +2
The radical hydrocarbon molecule CH is widely detected in various stages of star and planet formation, and has emerged as a useful tracer of high-C/O gas within the photochemic…
The SOFIA Massive (SOMA) Star Formation Survey. V. Clustered Protostars
Zoie Telkamp, Ruben Fedriani, Jonathan C. Tan +16
We present m SOFIA-FORCAST images of seven regions of ``clustered" star formation as part of the SOFIA Massive (SOMA) Star Formation Survey. We identify a total of 34…
The SOFIA Massive (SOMA) Star Formation Q-band follow-up I. Carbon-chain chemistry of intermediate-mass protostars
Kotomi Taniguchi, Prasanta Gorai, Jonathan C. Tan +10
Evidence for similar chemical characteristics around low- and high-mass protostars has been found: in particular, a variety of carbon-chain species and complex organic molecules (C…
