PROJECT-J: the shocking H2 outflow from HH46
Maria Gabriela Navarro, Brunella Nisini, Teresa Giannini +14
We analyze the H2 emission observed in the HH46 Class I system as part of PROJECT-J (Protostellar Jets Cradle Tested with JWST), to investigate the origin and excitation of the war…
A Mid-Infrared Spectroscopic Study of Young Stellar Objects in the SMC Region NGC 346: JWST Detects Dust, Accretion, Ices and Outflows
Nolan Habel, Omnarayani Nayak, Patrick J. Kavanagh +13
We present mid-infrared spectroscopic observations of intermediate- to high-mass young stellar objects (YSOs) in the low-metallicity star-forming region NGC 346 located within the…
The JWST/MIRI view of the planetary nebula NGC 6302 I.: a UV irradiated torus and a hot bubble triggering PAH formation
Mikako Matsuura, Kevin Volk, Patrick Kavanagh +34
NGC 6302 is a spectacular bipolar planetary nebula (PN) whose spectrum exhibits fast outflows and highly ionized emission lines, indicating the presence of a very hot central star…
JWST observations of the Ring Nebula (NGC 6720) -- II. PAH emission
Nicholas Clark, Els Peeters, Nick L. J. Cox +16
Polycyclic aromatic hydrocarbons (PAHs) and carbonaceous dust have been observed in clumpy circumstellar environments, yet their formation and evolutionary pathways in such environ…
JWST Observations of Young protoStars (JOYS): overview of program and early results
E. F. van Dishoeck, Ł. 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, 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…
JWST observations of segregated CO and CO ices in protostellar envelopes
N. G. C. Brunken, A. C. A. Boogert, E. F. van Dishoeck +13
The evolution of interstellar ices can be studied with thermal tracers such as the vibrational modes of CO ice that show great diversity depending on their local chemical and t…
Extended source fringe flats for the JWST MIRI Medium Resolution Spectrometer
N. Crouzet, M. Mueller, B. Sargent +17
The detectors of the JWST Mid-Infrared Instrument (MIRI) Medium Resolution Spectrometer (MRS) form low-finesse resonating cavities that cause periodic count rate modulations (fring…
JWST observations of the Ring Nebula (NGC 6720): III. A dusty disk around its Central Star
Raghvendra Sahai, Griet Van de Steene, Peter van Hoof +16
The planetary nebula NGC 6720, also known as the ``Ring Nebula", is one of the most iconic examples of nearby planetary nebulae whose morphologies present a challenge to our theore…
JOYS: The [D/H] abundance derived from protostellar outflows across the Galactic disk measured with JWST
L. Francis, E. F. van Dishoeck, A. Caratti o Garatti +8
The total deuterium abundance [D/H] in the universe is set by just two processes: the creation of deuterium in Big Bang Nucleosynthesis at an abundance of [D/H]$=2.58\pm0.13\times1…
