Constraining the Stellar Masses and Origin of the Protostellar VLA 1623 System
Sarah I Sadavoy, Patrick Sheehan, John J. Tobin +6
We present ALMA Band 7 molecular line observations of the protostars within the VLA 1623 system. We map CO (3 - 2) in the circumbinary disk around VLA 1623A and the outflow…
The factors that influence protostellar multiplicity I: Gas temperature, density, and mass in Perseus with Nobeyama
N. M. Murillo, C. M. Fuchs, D. Harsono +9
Protostellar multiplicity is common at all stages and mass ranges. However, the factors that determine the multiplicity of protostellar systems have not been systematically charact…
Identification of hot gas around low-mass protostars
Merel L. R. van 't Hoff, Edwin A. Bergin, Penelope Riley +3
The low carbon content of Earth and primitive meteorites compared to the Sun and interstellar grains suggests that carbon-rich grains were destroyed in the inner few astronomical u…
JWST detections of amorphous and crystalline HDO ice toward massive protostars
Katerina Slavicinska, Ewine F. van Dishoeck, Łukasz Tychoniec +19
This work aims to utilize the increased sensitivity and resolution of the JWST to quantify the HDO/HO ratio in ices toward young stellar objects (YSOs) and to determine if th…
JWST/MIRI detection of suprathermal OH rotational emissions: probing the dissociation of the water by Lyman alpha photons near the protostar HOPS 370
David A. Neufeld, P. Manoj, Himanshu Tyagi +22
Using the MIRI/MRS spectrometer on JWST, we have detected pure rotational, suprathermal OH emissions from the vicinity of the intermediate-mass protostar HOPS 370 (OMC2/FIR3). Thes…
JWST observations of CO ice: Tracing the chemical environment and thermal history of ices in protostellar envelopes
Nashanty G. C. Brunken, Will R. M. Rocha, Ewine F. van Dishoeck +38
The structure and composition of simple ices can be modified during stellar evolution by protostellar heating. Key to understanding the involved processes are thermal and chemical…
