PDRs4All VIII: Mid-IR emission line inventory of the Orion Bar
Dries Van De Putte, Raphael Meshaka, Boris Trahin +135
Mid-infrared emission features probe the properties of ionized gas, and hot or warm molecular gas. The Orion Bar is a frequently studied photodissociation region (PDR) containing l…
A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk
Olivier Berné, Emilie Habart, Els Peeters +143
Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
PDRs4All VII. The 3.3 m aromatic infrared band as a tracer of physical properties of the ISM in galaxies
Ilane Schroetter, Olivier Berné, Christine Joblin +9
Aromatic infrared bands (AIBs) are a set of broad emission bands at 3.3, 6.2, 7.7, 8.6, 11.2, and 12.7 m, seen in the infrared spectra of most galaxies. With JWST, the 3.3 m…
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…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula
Emilie Habart, Els Peeters, Olivier Berné +139
The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…
PDRs4All: A JWST Early Release Science Program on radiative feedback from massive stars
Olivier Berné, Émilie Habart, Els Peeters +134
Massive stars disrupt their natal molecular cloud material through radiative and mechanical feedback processes. These processes have profound effects on the evolution of interstell…
Breakdown products of gaseous polycyclic aromatic hydrocarbons investigated with infrared ion spectroscopy
A. Petrignani, M. Vala, J. R. Eyler +5
We report on a common fragment ion formed during the electron-ionization-induced fragmentation of three different three-ring polycyclic aromatic hydrocarbons (PAHs), fluorene (C$_{…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons in the 3 micron region: role of hydrogenation and alkylation
E. Maltseva, C. J. Mackie, A. Candian +6
Aims. We aim to elucidate the spectral changes in the 3 micron region that result from chemical changes in the molecular periphery of polycyclic aromatic hydrocarbons (PAHs) with e…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons in the 3 μm region: Role of periphery
Elena Maltseva, Annemieke Petrignani, Alessandra Candian +5
In this work we report on high-resolution IR absorption studies that provide a detailed view on how the peripheral structure of irregular polycyclic aromatic hydrocarbons (PAHs) af…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons: the realm of anharmonicity
Elena Maltseva, Annemieke Petrignani, Alessandra Candian +6
We report on an experimental and theoretical investigation of the importance of anharmonicity in the 3 micron CH stretching region of Polycyclic Aromatic Hydrocarbon (PAH) molecule…
