Ångstrom depth resolution with chemical specificity at the liquid-vapor interface
R. Dupuy, J. Filser, C. Richter +13
The determination of depth profiles across interfaces is of primary importance in many scientific and technological areas. Photoemission spectroscopy is in principle well suited fo…
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…
Mechanism of Indirect Photon-induced Desorption at the Water Ice Surface
R. Dupuy, M. Bertin, G. Féraud +8
Electronic excitations near the surface of water ice lead to the desorption of adsorbed molecules, through a so far debated mechanism. A systematic study of photon-induced indirect…
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…
Electron-stimulated desorption from molecular ices in the sub-keV regime
Rémi Dupuy, Michal Haubner, Bernard Henrist +2
Electron-stimulated desorption (ESD) of cryosorbed molecules on surfaces is a process of relevance to fields as varied as vacuum dynamics in accelerators and astrochemistry. While…
Desorption of neutrals, cations and anions from core-excited amorphous solid water
R. Dupuy, G. Féraud, M Bertin +7
Core-excitation of water ice releases many different molecules and ions in the gas phase. Studying these desorbed species and the underlying mechanisms can provide useful informati…
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…
