Physical conditions in PDRs revealed by IGRINS ro-vibrational H2 observations

Aurélien Piluso, Vincent Maillard, Raphael Meshaka +10

We compare H2 high ro-vibrational observations of 5 PDRs (S140, IC63, Horsehead Nebula, NGC 2023 and Orion Bar) obtained with the IGRINS spectrograph to PDR models produced with th…

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…

PDRs4All IX. Sulfur elemental abundance in the Orion Bar

Asunción Fuente, Evelyne Roueff, Franck Le Petit +31

One of the main problems in astrochemistry is determining the amount of sulfur in volatiles and refractories in the interstellar medium. The detection of the main sulfur reservoirs…

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…

Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk

Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53

Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…

PDRs4All. V. Modelling the dust evolution across the illuminated edge of the Orion Bar

M. Elyajouri, N. Ysard, A. Abergel +31

We study the emission of dust grains within the Orion Bar - a well-known, highly far-UV (FUV)-irradiated PDR. The Orion Bar because of its edge-on geometry provides an exceptional…

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…
