Inelastic H + H Collision rates and their impact in the determination of the excitation temperature of H
Daniel Felix-Gonzalez, Pablo del Mazo-Sevillano, Alfredo Aguado +5
Context. In dffuse interstellar clouds the excitation temperature derived from the lowest levels of H is systematically lower than that derived from H2. The differences may b…
Toward a robust physical and chemical characterization of heterogeneous lines of sight: The case of the Horsehead nebula
Léontine Ségal, Antoine Roueff, Jérôme Pety +28
Dense cold molecular cores/filaments are surrounded by an envelope of translucent gas. Some of the low-J emission lines of CO and HCO isotopologues are more sensitive to the co…
Quantifying the informativity of emission lines to infer physical conditions in giant molecular clouds. I. Application to model predictions
Lucas Einig, Pierre Palud, Antoine Roueff +29
Observations of ionic, atomic, or molecular lines are performed to improve our understanding of the interstellar medium (ISM). However, the potential of a line to constrain the phy…
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…
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…
