Accretion onto the Embedded Protostar L1527 IRS: Insights from JWST NIRSpec and MIRI Observations
W. Blake Drechsler, John J. Tobin, Patrick D. Sheehan +12
Accretion is the primary driver of protostellar evolution, regulating mass assembly and shaping the physical and chemical environments of young stellar objects. Quantifying accreti…
Protostars at Subsolar Metallicity: First Detection of Large Solid-state Complex Organic Molecules in the Large Magellanic Cloud
Marta SewiÅo, Will R. M. Rocha, Martijn van Gelder +11
We present the results of James Webb Space Telescope observations of the protostar ST6 in the Large Magellanic Cloud (LMC) with the Medium Resolution Spectrograph of the Mid-Infrar…
UV-irradiated outflows from low-mass protostars in Ophiuchus with JWST/MIRI
I. M. Skretas, A. Karska, L. Francis +7
The main accretion phase of protostars is characterized by the ejection of material in the form of jets/outflows. External UV irradiation can potentially have a significant impact…
JWST Observations of Young protoStars (JOYS): overview of program and early results
E. F. van Dishoeck, Å. Tychoniec, W. R. M. Rocha +34
The embedded phase is a crucial period in the development of a young star. Mid-IR observations, now possible with JWST with unprecedented sensitivity, spectral resolution and sharp…
HDO ice detected toward an isolated low-mass protostar with JWST
Katerina Slavicinska, Åukasz Tychoniec, MarÃa Gabriela Navarro +15
Water is detected in environments representing every stage of star and solar system formation, but its chemical evolution throughout these stages remains poorly constrained. Deuter…
JWST Observations of Young protoStars (JOYS). Overview of gaseous molecular emission and absorption in low-mass protostars
M. L. van Gelder, L. Francis, E. F. van Dishoeck +17
The MIRI-MRS instrument onboard JWST allows for probing the molecular gas composition at mid-IR wavelengths at unprecedented resolution and sensitivity. It is important to study th…
