PDRs4All XVII: Formation and excitation of HD in photodissociation regions. Application to the Orion Bar
Marion Zannese, Jacques Le Bourlot, Evelyne Roueff +12
The James Webb Space Telescope enabled the first detection of several rovibrational emission lines of HD in the Orion Bar, a prototypical photodissociation region. This provides an…
PDRs4All XV: CH radical and H molecular ion in the irradiated protoplanetary disk d203-506
I. Schroetter, O. Berné, J. R. Goicoechea +20
Most protoplanetary disks experience a phase in which they are subjected to strong ultraviolet radiation from nearby massive stars. This UV radiation can substantially alter their…
H3+ in irradiated protoplanetary disks: Linking far-ultraviolet radiation and water vapor
Javier R. Goicoechea, Octavio Roncero, Evelyne Roueff +3
The likely JWST detection of vibrationally excited H3+ emission in Orion's irradiated disk system d203-506 raises the important question of whether cosmic-ray ionization is enhance…
PDRs4All XI. Detection of infrared CH and CH rovibrational emission in the Orion Bar and disk d203-506: evidence of chemical pumping
Marion Zannese, Benoît Tabone, Emilie Habart +20
The methylidyne cation (CH) and the methyl cation (CH) are building blocks of organic molecules, yet their coupled formation and excitation mechanisms remain mainly unpro…
PDRs4All. X. ALMA and JWST detection of neutral carbon in the externally irradiated disk d203-506: Undepleted gas-phase carbon
Javier R. Goicoechea, J. Le Bourlot, J. H. Black +26
The gas-phase abundance of carbon, x_C = C/H, and its depletion factors are essential parameters for understanding the gas and solid compositions that are ultimately incorporated i…
OH mid-infrared emission as a diagnostic of HO UV photodissociation. III. Application to planet-forming disks
Benoît Tabone, Ewine F. van Dishoeck, John H. Black
JWST gives a unique access to the physical and chemical structure of inner disks (~au), where the majority of the planets are forming. However, the interpretation of mid-infra…
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…
Protonated acetylene in the z=0.89 molecular absorber toward PKS1830-211
S. Muller, R. Le Gal, E. Roueff +7
We report the first interstellar identification of protonated acetylene, C2H3+, a fundamental hydrocarbon, in the z=0.89 molecular absorber toward the gravitationally lensed quasar…
OH as a probe of the warm water cycle in planet-forming disks
Marion Zannese, Benoît Tabone, Emilie Habart +52
Water is a key ingredient for the emergence of life as we know it. Yet, its destruction and reformation in space remains unprobed in warm gas. Here, we detect the hydroxyl radical…
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…
The ALMA view of UV irradiated cloud edges: unexpected structures and processes
Javier R. Goicoechea, S. Cuadrado, J. Pety +8
Far-UV photons (E<13.6 eV) from hot massive stars regulate, or at least influence, the heating, ionization, and chemistry of most of the neutral interstellar medium. Investigating…
First detection of [N II] 205 micrometer absorption in interstellar gas
C. M. Persson, M. Gerin, B. Mookerjea +8
We present high resolution [NII] 205 micrometer ^3P_1-^3P_0 spectra obtained with Herschel-HIFI towards a small sample of far-infrared bright star forming regions in the Galactic p…
