Influence of the nano-grain depletion in photon-dominated regions: Application to the gas physics and chemistry in the Horsehead
T. Schirmer, E. Habart, N. Ysard +7
The large disparity in physical conditions from the diffuse interstellar medium (ISM) to denser clouds such as photon-dominated regions (PDRs) triggers an evolution of the dust pro…
C18O, 13CO, and 12CO abundances and excitation temperatures in the Orion B molecular cloud: An analysis of the precision achievable when modeling spectral line within the Local Thermodynamic Equilibrium approximation
Antoine Roueff, Maryvonne Gerin, Pierre Gratier +23
CO isotopologue transitions are routinely observed in molecular clouds to probe the column density of the gas, the elemental ratios of carbon and oxygen, and to trace the kinematic…
Chlorine-bearing molecules in molecular absorbers at intermediate redshifts
S. H. J. Wallstrom, S. Muller, E. Roueff +3
We use observations of chlorine-bearing species in molecular absorbers at intermediate redshifts to investigate chemical properties and Cl/Cl isotopic ratios in the a…
Spatially resolved l-c3h+ emission in the horsehead photodissociation region: Further evidence for a top-down hydrocarbon chemistry
V. V. Guzmán, J. Pety, J. R. Goicoechea +4
Small hydrocarbons, such as C2H, C3H and C3H2 are more abundant in photo-dissociation regions (PDRs) than expected based on gas-phase chemical models. To explore the hydrocarbon ch…
