JOYS: Launch and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST MIRI
Łukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +25
Protostellar winds can theoretically lift solids from the planet-forming disks, but direct evidence for launched dust has been scarce so far. Numerous atomic lines that are unique…
JOYS: A JWST/MIRI survey of the evolution of H winds and jets from low-mass protostars
L. Francis, Ł. Tychoniec, E. F. van Dishoeck +20
Protostellar outflows display wide-angle winds and collimated jets, the magnetocentrifugal launching of which enables accretion onto the protostar. The majority of the outflow mass…
Unlocking accretion rate diagnostics for high-mass protostars using JWST/MIRI HI lines
S. D. Reyes-Reyes, H. Beuther, E. F. van Dishoeck +14
While many aspects of high-mass star formation have been investigated, the accretion onto the central protostars is one of the most fundamental but less explored physical propertie…
JOYS: JWST MIRI/MRS spectra of the inner 500 au region of the L1527 IRS bipolar outflow
R. Devaraj, E. F. van Dishoeck, T. P. Ray +12
This study characterized the physical and kinematic properties within the innermost 500 au region of the L1527 bipolar outflow, a class 0/I low-mass protostar using JWST MIRI/MRS s…
HDO ice detected toward an isolated low-mass protostar with JWST
Katerina Slavicinska, Łukasz Tychoniec, María 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…
Mid-infrared extinction curve for protostellar envelopes from JWST-detected embedded jet emission: the case of TMC1A
K. D. Assani, Z. -Y. Li, J. P. Ramsey +15
Context: Dust grains are key components of the interstellar medium and play a central role in star formation, acting as catalysts for chemical reactions and as building blocks of p…
JOYS+ study of solid state C/C isotope ratios in protostellar envelopes: Observations of CO and CO ice with JWST
N. G. C. Brunken, E. F. van Dishoeck, K. Slavicinska +12
The carbon isotope ratio is a powerful tool for studying the evolution of stellar systems. Recent detections of CO isotopologues in disks and exoplanet atmospheres pointed towards…
JWST Observations of Young protoStars (JOYS). HH 211: the textbook case of a protostellar jet and outflow
A. Caratti o Garatti, T. P. Ray, P. J. Kavanagh +22
We use the James Webb Space Telescope (JWST) and its Mid-Infrared Instrument (MIRI) (5-28 um), to study the embedded HH 211 flow. We map a 0.95'x0.22' region, covering the full ext…
The most variable VVV sources: eruptive protostars, dipping giants in the Nuclear Disc and others
P. W. Lucas, L. C. Smith, Z. Guo +16
We have performed a comprehensive search of a VISTA Variables in the Via Lactea (VVV) database of 9.5 yr light curves for variable sources with mag, aiming to provide…
