Photocleavage of aliphatic C--C bonds in the interstellar medium
Guillermo Tajuelo-Castilla, Jesús I. Mendieta-Moreno, Mario Accolla +6
Ultraviolet (UV) processing in the insterstellar medium (ISM) induces the dehydrogenation of hydrocarbons. Aliphatics, including alkanes, are present in different interstellar envi…
INFRA-ICE: an ultra-high vacuum experimental station for laboratory astrochemistry
Gonzalo Santoro, Jesús. M. Sobrado, Guillermo Tajuelo-Castilla +7
Laboratory astrochemistry aims at simulating in the laboratory some of the chemical and physical processes that operate in different regions of the Universe. Amongst the diverse as…
Silicon and hydrogen chemistry under laboratory conditions mimicking the atmosphere of evolved stars
Mario Accolla, Gonzalo Santoro, Pablo Merino +10
Silicon is present in interstellar dust grains, meteorites and asteroids, and to date thirteen silicon-bearing molecules have been detected in the gas-phase towards late-type stars…
The chemistry of cosmic dust analogues from C, C, and CH in C-rich circumstellar envelopes
Gonzalo Santoro, Lidia Martínez, Koen Lauwaet +13
Interstellar carbonaceous dust is mainly formed in the innermost regions of circumstellar envelopes around carbon-rich asymptotic giant branch (AGB) stars. In these highly chemical…
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…
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…
