JWST observations of photodissociation regions. IV. Carbonaceous emission band sub-components in NGC 7023 have distinct spatial distributions
D. Van De Putte, K. D. Gordon, K. Misselt +10
We analyze JWST spectroscopy of the northwest filament of NGC7023, where the relatively soft radiation field results in a photodissociation region with an extended atomic hydrogen…
JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR
M. Elyajouri, A. Abergel, N. Ysard +19
Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…
JWST observations of photodissociation regions: II. Warm molecular Hydrogen spectroscopy in the Horsehead nebula
M. Zannese, P. Guillard, A. Abergel +16
H2 is the most abundant molecule in the interstellar medium and is a useful tool to study photodissociation regions, where radiative feedback from massive stars on molecular clouds…
JWST observations of the Horsehead photon-dominated region I. First results from multi-band near- and mid-infrared imaging
A. Abergel, K. Misselt, K. D. Gordon +14
The JWST has captured the sharpest IR images ever taken of the Horsehead nebula, a prototypical moderately irradiated PDR that is fully representative of most of the UV-illuminated…
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…
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 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…
A high resolution study of near-IR diffuse interstellar bands, search for small scale structure, time variability and stellar features
J. V. Smoker, A. Müller, A. Monreal Ibero +13
Diffuse interstellar bands comprise hundreds of absorption features in the ISM. Most DIBs are observed in the optical, but some are in the IR. We observed 76 early-type stars at R=…
The EDIBLES survey V: Line profile variations in the 5797, 6379, and 6614 diffuse interstellar bands as a tool to constrain carrier sizes
Heather MacIsaac, Jan Cami, Nick L. J. Cox +13
Several diffuse interstellar bands (DIBs) have profiles with resolved sub-peaks that resemble rotational bands of large molecules. Analysis of these profiles can constrain the size…
Updated extraction of the APOGEE 1.5273 μm diffuse interstellar band: a Planck view on the carrier depletion in dense cores
Meriem Elyajouri, Rosine Lallement
The latest SDSS/APOGEE data release DR14 has provided an increased number of stellar spectra in the H band and associated stellar models using an innovative algorithm known as The…
The EDIBLES survey III. C2-DIBs and their profiles
M. Elyajouri, R. Lallement, N. L. J. Cox +6
The so-called C2-DIBs are a class of very weak bands that fall in the blue part of the optical spectrum and are associated with high column densities of the C2 molecule. DIB profil…
3D maps of interstellar dust in the Local Arm: using , 2MASS and APOGEE-DR14
R. Lallement, L. Capitanio, L. Ruiz-Dern +6
Gaia data and stellar surveys open the way to the construction of detailed 3D maps of the Galactic interstellar (IS) dust based on the synthesis of star distances and extinctions.…
EDIBLES II. On the detectability of C60+ bands
R. Lallement, N. L. J. Cox, J. Cami +8
Gas phase spectroscopic laboratory experiments for the buckminsterfullerene cation C60+ resulted in accurate rest wavelengths for five C60+ transitions that have been compared with…
The ESO Diffuse Interstellar Bands Large Exploration Survey: EDIBLES I. Project description, survey sample and quality assessment
Nick Cox, Jan Cami, Amin Farhang +27
The carriers of the diffuse interstellar bands (DIBs) are largely unidentified molecules ubiquitously present in the interstellar medium (ISM). After decades of study, two strong a…
Three-dimensional mapping of the local interstellar medium with composite data
Letizia Capitanio, Rosine Lallement, Jean Luc Vergely +2
Three-dimensional maps of the Galactic interstellar medium are general astrophysical tools. Reddening maps may be based on the inversion of color excess measurements for individual…
Near-infrared diffuse interstellar bands in APOGEE telluric standard star spectra: weak bands and comparisons with optical counterparts
M. Elyajouri, R. Lallement, A. Monreal-Ibero +2
Information on the existence and properties of diffuse interstellar bands (DIBs) outside the optical domain is still limited. Additional infra-red (IR) measurements and IR-optical…
