X-ray induced desorption and photochemistry in CO ice
R. Dupuy, M. Bertin, G. Féraud +8
We report an investigation of X-ray induced desorption of neutrals, cations and anions from CO ice. The desorption of neutral CO, by far the most abundant, is quantified and discus…
Vacuum-UV photodesorption from compact Amorphous Solid Water : photon energy, isotopic and temperature effects
Jean-Hugues Fillion, Rémi Dupuy, Géraldine Féraud +9
Vacuum-UV (VUV) photodesorption from water-rich ice mantles coating interstellar grains is known to play an important role in the gas-to-ice ratio in star- and planet-forming regio…
Complex organic molecules in protoplanetary disks: X-ray photodesorption from methanol-containing ices. Part II -- Mixed methanol-CO and methanol-H2O ices
R. Basalgète, R. Dupuy, G. Féraud +8
Astrophysical observations show complex organic molecules (COMs) in the gas phase of protoplanetary disks. X-rays emitted from the central young stellar object (YSO) that irradiate…
Complex organic molecules in protoplanetary disks : X-ray photodesorption from methanol-containing ices. Part I -- Pure methanol ices
R. Basalgète, R. Dupuy, G. Féraud +8
Astrophysical observations show complex organic molecules (COMs) in the gas phase of protoplanetary disks. X-rays emitted from the central young stellar object (YSO) that irradiate…
Vacuum ultraviolet photodesorption and photofragmentation of formaldehyde-containing ices
Géraldine Féraud, Mathieu Bertin, Claire Romanzin +7
Non-thermal desorption from icy grains containing HCO has been invoked to explain the observed HCO gas phase abundances in ProtoPlanetary Disks (PPDs) and Photon Dominated…
Synchrotron radiation interaction with cryosorbed layers for astrochemical investigations
Rémi Dupuy, Mathieu Bertin, Géraldine Féraud +8
Photon-stimulated desorption (PSD) is a process of interest for the two seemingly unrelated topics of accelerator vacuum dynamics and astrochemistry. Here we present an approach to…
Spectrally-resolved UV photodesorption of CH4 in pure and layered ices
Rémi Dupuy, Mathieu Bertin, Géraldine Féraud +6
Context. Methane is among the main components of the ice mantles of insterstellar dust grains, where it is at the start of a rich solid-phase chemical network. Quantification of th…
Unusual behavior in the first excited state lifetime of catechol
Martin Weiler, Mitsuhiko Miyazaki, Géraldine Féraud +4
We are presenting vibrationally selective pump-probe measurements of the first electronic excited-state (pp*) lifetime of jet-cooled neutral catechol (1,2-dihydroxybenzene). The li…
