Full textFormed in the dense clouds, icy mantles are condensates of small molecules on solid grains. These icy mantles are promising sites for rich chemical processes, where complex organic molecules can form, as these mantles are continuously exposed to ionizing radiation. Once dense clouds transform into an accretion disc and eventually into a planetary system, these icy mantles may potentially contribute to the reservoir of the complex molecules of the planets.In this thesis, the effects of ion irradiation on two aromatic molecules, pyridine and pyrene were investigated. The samples were exposed to ion irradiation at the GANIL (Caen, France) and ATOMKI (Debrecen, Hungary) ion beam facilities. Their evolution was monitored using in-situ infrared spectroscopy. It was found that the initial structure (amorphous or crystalline) and the irradiation temperature do not affect the destruction cross section of pure pyridine. Additionally, it was observed that the local dose is not a key parameter as previously assumed. Indeed, since the destruction of pyrene caused by heavy ions, starting from C, is significantly greater than that caused by lighter ions such as H and He for the same deposited local dose. For both molecules, a significant increase in the destruction cross section was observed for decreasing molecule concentration in the water matrix. The half-life time of pyridine and pyrene in dense clouds was estimated to be around 13 and 20 millions of years, respectively. This suggests that once formed in these environments, they could survive and contribute to planetary formation

Full textIces can exist in our solar system for example on comets, the moons of Jupiter and Saturn, and trans-Neptunian objects. In the cold interstellar medium, they form thin layers on dust grains. Water (H2O) is the most abundant molecules in those ices, which are continuously exposed to the irradiation by cosmic rays, solar wind, and ions trapped in the magnetosphere of the giant planets. Simulation in the laboratory compared to telescopic observations can provide information to understand the large variety of radiation induced physicochemical processes. Therefore, we simulated the effects of swift heavy ion (cosmic ray analogs) and slow ion (solar wind, magnetosphere ions) irradiation of water ice at different beam lines of the GANIL accelerator facility. Fourier transform infrared spectroscopy (FTIR) was used to analyze the ices. The irradiation induced structural changes of water ice such as amorphization and compaction were studied. The efficiency to amorphize and compact the ice was established as a function of projectile stopping power with several swift heavy ions. Furthermore, by implantation of sulfur ions in water ice, the formation yield of sulfuric acid was measured and found to increase with projectile energy. From comparison to measure sulfur ion fluxes and sulfuric acid concentrations by the Galileo spacecraft, strong evidence was found that H2SO4 on Europa’s surface can be formed by sulfur ion implantation of magnetosphere ions in water ice. Finally, we also performed a first preliminary experiment to study the radiation induced chemistry with a carbonaceous solid substrate covered with a NH3+H2O ice mantle

Full textThe deposition of energy in the form of electronic excitations in molecules condensed on cold surfaces (10-100 K) can lead to the desorption of some of these molecules. This basic surface science process has consequences in a variety of fields, two of which are of concern here : astrochemistry and vacuum dynamics. Photon and Electron-Induced desorption are studied in this manuscript for thin films of condensed molecules (ices), e.g. CO, H2O, NO or CH4. The first objective is to obtain a quantification of the desorption of the various desorbing species, and to look for the parameters that affect the efficiency of the process. The second objective is to understand the mechanisms of evolution and relaxation of the initial electronic excitations that lead to desorption. Photon-induced desorption is studied at LERMA using synchrotron radiation in the VUV range (5-14 eV) and soft X-ray range (520-600 eV). This allows to obtain spectrally-resolved information, which is crucial both for model implementation and fundamental understanding of the mechanisms. Electron-induced desorption is studied at CERN in the 150-2000 eV range. The results expand the available data on UV photodesorption and allow to determine the relevance of electron or X-ray desorption for astrochemistry. Progress has also been made on the understanding of mechanisms, particularly on the role of energy or particle transport from the bulk to the surface of the ice, on indirect desorption, or on the desorption of ions in the soft X-ray range. A new experimental set-up has also been developed at LERMA for laser desorption and laser spectroscopy experiments, allowing quantum-state and kinetic energy resolved measurements of desorbed molecules
