Reaction Mechanisms and Kinetics of CN and CCH with H2CS: Implications for Interstellar Sulfur Chemistry
Boutheïna Kerkeni, Ghofrane Ouerfelli, Nicole Feautrier +1
We report an ab initio and master-equation investigation of the gas-phase reactions of thioformaldehyde (H2CS) with CN and CCH radicals, motivated by the recent detection of the S-…
Theoretical investigations of propyl-cyanide formation in gas phase and on ice mantles
Boutheina Kerkeni, Victoria Gamez, Ghofrane Ouerfelli +2
Propyl cyanide (PrCN) (C3H7CN) with both linear and branched isomers is ubiquitous in interstellar space and is important for astrochemistry as it is one of the most complex molecu…
Ca line formation in late-type stellar atmospheres: I. The model atom
Y. Osorio, K. Lind, P. S. Barklem +2
Context. Departures from local thermodynamic equilibrium (LTE) distort the calcium abundance derived from stellar spectra in various ways, depending on the lines used and the stell…
Mg line formation in late-type stellar atmospheres: I. The model atom
Y. Osorio, P. S. Barklem, K. Lind +4
Mg is often traced in late-type stars using lines of neutral magnesium, which is expected to be subject to departures from LTE. The astrophysical importance of Mg as well as its re…
Hyperfine excitation of NH by H: Toward a revision of NH abundance in cold molecular clouds
François Lique, Fabien Daniel, Laurent Pagani +1
The modelling of emission spectra of molecules seen in interstellar clouds requires the knowledge of collisional rate coefficients. Among the commonly observed species, NH…
Inelastic Mg+H collision data for non-LTE applications in stellar atmospheres
P. S. Barklem, A. K. Belyaev, A. Spielfiedel +2
Rate coefficients for inelastic Mg+H collisions are calculated for all transitions between the lowest seven levels and the ionic state (charge transfer). The rate coefficients are…
On inelastic hydrogen atom collisions in stellar atmospheres
P. S. Barklem, A. K. Belyaev, M. Guitou +3
The influence of inelastic hydrogen atom collisions on non-LTE spectral line formation has been, and remains to be, a significant source of uncertainty for stellar abundance analys…
