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…
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…
Density distributions, magnetic field structures and fragmentation in high-mass star formation
H. Beuther, C. Gieser, J. D. Soler +19
Methods: Observing the large pc-scale Stokes I mm dust continuum emission with the IRAM 30m telescope and the intermediate-scale (<0.1pc) polarized submm dust emission with the Sub…
PDRs4All III: JWST's NIR spectroscopic view of the Orion Bar
Els Peeters, Emilie Habart, Olivier Berne +135
(Abridged) We investigate the impact of radiative feedback from massive stars on their natal cloud and focus on the transition from the HII region to the atomic PDR (crossing the i…
Multi-wavelength modelling of the circumstellar environment of the massive proto-star AFGL 2591 VLA 3
F. A. Olguin, M. G. Hoare, K. G. Johnston +13
We have studied the dust density, temperature and velocity distributions of the archetypal massive young stellar object (MYSO) AFGL 2591. Given its high luminosity ($L=2 \times 10^…
Core fragmentation and Toomre stability analysis of W3(H2O): A case study of the IRAM NOEMA large program CORE
A. Ahmadi, H. Beuther, J. C. Mottram +30
The fragmentation mode of high-mass molecular clumps and the properties of the central rotating structures surrounding the most luminous objects have yet to be comprehensively char…
Cloud Disruption via Ionized Feedback: Tracing Pillar Dynamics in Vulpecula
P. D. Klaassen, J. C. Mottram, J. E. Dale +1
The major physical processes responsible for shaping and sculpting pillars in the clouds surrounding massive stars (i.e. the `Pillars of Creation') are now being robustly incorpora…
