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…
X-ray photodesorption from water ice in protoplanetary disks and X-ray dominated regions
Rémi Dupuy, Mathieu Bertin, Géraldine Féraud +10
Water is the main constituent of interstellar ices, and it plays a key role in the evolution of many regions of the interstellar medium, from molecular clouds to planet-forming dis…
The efficient photodesorption of nitric oxide (NO) ices A laboratory astrophysics study
R. Dupuy, G. Féraud, M. Bertin +8
The study and quantification of UV photon-induced desorption of frozen molecules furthers our understanding of the chemical evolution of cold interstellar regions. Nitric oxide (NO…
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…
UV photodesorption of methanol in pure and CO-rich ices: desorption rates of the intact molecule and of the photofragments
Mathieu Bertin, Claire Romanzin, Mikhail Doronin +6
Wavelength dependent photodesorption rates have been determined using synchrotron radiation, for condensed pure and mixed methanol ice in the 7 -- 14 eV range. The VUV photodesorpt…
Indirect ultraviolet photodesorption from CO:N2 binary ices - an efficient grain-gas process
Mathieu Bertin, Edith C. Fayolle, Claire Romanzin +7
UV ice photodesorption is an important non-thermal desorption pathway in many interstellar environments that has been invoked to explain observations of cold molecules in disks, cl…
Wavelength-dependent UV photodesorption of pure N2 and O2 ices
Edith C. Fayolle, Mathieu Bertin, Claire Romanzin +7
Ultraviolet photodesorption of molecules from icy interstellar grains can explain observations of cold gas in regions where thermal desorption is negligible. This non-thermal desor…
