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…
Deuteration of ammonia with D atoms on oxidized partly ASW covered graphite surface
Henda Chaabouni, Marco Minissale, Saoud Baouche +1
The deuteration of ammonia by D atoms has been investigated experimentally in the sub-monolayer regime on realistic analogues of interstellar dust grain surfaces. About 0.8 monolay…
Quantum tunneling of oxygen atoms on very cold surfaces
M. Minissale, E. Congiu, S. Baouche +7
Any evolving system can change of state via thermal mechanisms (hopping a barrier) or via quantum tunneling. Most of the time, efficient classical mechanisms dominate at high tempe…
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…
Sticking coefficient of hydrogen and deuterium on silicates under interstellar conditions
H. Chaabouni, H. Bergeron, S. Baouche +5
Sticking of H and D atoms on interstellar dust grains is the first step in molecular hydrogen formation, which is a key reaction in the InterStellar Medium (ISM). After studying th…
Changes in the morphology of interstellar ice analogues after hydrogen atom exposure
Mario Accolla, Emanuele Congiu, François Dulieu +6
The morphology of water ice in the interstellar medium is still an open question. Although accretion of gaseous water could not be the only possible origin of the observed icy mant…
Gas temperature dependent sticking of hydrogen on cold amorphous water ice surfaces of interstellar interest
E. Matar, H. Bergeron, F. Dulieu +3
Using the King & Wells method, we present experimental data on the dependence of the sticking of molecular hydrogen and deuterium on the beam temperature onto non- porous amorphous…
Experimental evidence for water formation via ozone hydrogenation on dust grains at 10 K
H. Mokrane, H. Chaabouni, M. Accolla +4
The formation of water molecules from the reaction between ozone (O3) and D-atoms is studied experimentally for the first time. Ozone is deposited on non-porous amorphous solid wat…
