Efficient Interstellar Grain Growth from High Sticking Coefficients on Amorphous Carbon Dust
Clarke J. Esmerian, Duncan Bossion, Francois Dulieu +8
Cosmic dust is the solid phase of the interstellar medium (ISM), classically assumed to be composed of carbonaceous and silicate grains with size distributions spanning …
Astrochemical models of interstellar ices: History matters
A. Clément, A. Taillard, V. Wakelam +6
Ice is ubiquitous in the interstellar medium. We model the formation of the main constituents of interstellar ices, including H2O, CO2 , CO, and CH3 OH. We strive to understand wha…
Thermal desorption of formamide and methylamine from graphite and amorphous water ice surfaces
Henda Chaabouni, Stephan Diana, Thanh Nguyen +1
Formamide (NH2CHO) and methylamine (CH3NH2) are known to be the most abundant amine-containing molecules in many astrophysical environments. The presence of these molecules in the…
H formation on interstellar dust grains: the viewpoints of theory, experiments, models and observations
Valentine Wakelam, Emeric Bron, Stephanie Cazaux +12
Molecular hydrogen is the most abundant molecule in the universe. It is the first one to form and survive photo-dissociation in tenuous environments. Its formation involves catalyt…
Oxygen diffusion and reactivity at low temperature on bare amorphous olivine-type silicate
M. Minissale, E. Congiu, F. Dulieu
The mobility of O atoms at very low temperatures is not generally taken into account, despite O diffusion would add to a series of processes leading to the observed rich molecular…
Efficient diffusive mechanisms of O atoms at very low temperatures on surfaces of astrophysical interest
E. Congiu, M. Minissale, S. Baouche +6
At the low temperatures of interstellar dust grains, it is well established that surface chemistry proceeds via diffusive mechanisms of H atoms weakly bound (physisorbed) to the su…
