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-…

Peculiarities in the infrared emission of PAH-C adducts
R. Barzaga, B. Kerkeni, D. A. GarcÃa-Hernández +7
The coexistence of PAHs and the C fullerene in different astrophysical environments can give rise to the formation of new complex species denoted as PAH-C adducts, wh…

Hydroxylated Mg-rich amorphous silicates as catalysts for molecular hydrogen formation in the interstellar medium
V. Mennella, T. Suhasaria, B. Kerkeni +1
We present results from an experimental study on the interaction of atomic deuterium with Mg-rich amorphous enstatite and forsterite type silicates. Infrared spectroscopy was used…
