Sustained oscillations in Interstellar chemistry models
Evelyne Roueff, Jacques Le Bourlot
Non-linear behavior in interstellar chemical models has been recognized for 25 years now. Different mechanisms account for the possibility of multiple fixed-points at steady state,…
Quantitative inference of the column densities from 3 mm molecular emission: A case study towards Orion B
Pierre Gratier, Jérôme Pety, Emeric Bron +21
Molecular hydrogen being unobservable in cold molecular clouds, the column density measurements of molecular gas currently rely either on dust emission observation in the far-IR or…
Tracers of the ionization fraction in dense and translucent gas: I. Automated exploitation of massive astrochemical model grids
Emeric Bron, Evelyne Roueff, Maryvonne Gerin +21
The ionization fraction plays a key role in the physics and chemistry of the neutral interstellar medium, from controlling the coupling of the gas to the magnetic field to allowing…
Gas phase Elemental abundances in Molecular cloudS (GEMS). II. On the quest for the sulphur reservoir in molecular clouds: the case
D. Navarro-Almaida, R. Le Gal, A. Fuente +30
Sulphur is one of the most abundant elements in the Universe. Surprisingly, sulphuretted molecules are not as abundant as expected in the interstellar medium, and the identity of t…
Detection of deuterated molecules, but not of lithium hydride, in the z=0.89 absorber toward PKS1830-211
S. Muller, E. Roueff, J. H. Black +8
Deuterium and lithium are light elements of high cosmological and astrophysical importance. In this work we report the first detection of deuterated molecules and a search for lith…
