The aim of this project is to experimentally study the interaction between highlycharged ions with the mixture H2O,CO2,CH4(10:1:1) astrophysical ice analogs in physicochemical condition similar to the ones found in interstellar dust regions, comets, transneptunians objects (TNO) and moons (for example Enceladus). As a first step, we will analyze experimental data obtained previously by th…
It has been shown through observations in the infrared from ISO (Infrared Space Observatory) and SST (Spitzer Space Telescope), the existence of astrophysical ices toward protostars. Among them, there are H2O, CO, CO2, NH3, CH3OH, CH4, HCOOH, H2CO, CH3CHO. In the same time of observations, several papers were published, showing the formation of complex molecules from simple one, through e…
Acetic acid and its isomers (methyl formate and glycolaldehyde have been detected in different space environments, for example, in molecular clouds associated with star-forming region. Their abundances relative to molecular hydrogen in different regions vary greatly among themselves, which would be related to different mechanisms of formation and destruction. In space, these chemical spec…

This project is a natural extension of the master project of Marina Gomes Rachid (FAPESP#2016/11334-5) on the effects of swift ions (15.7 MeV O+5) on astrophysical ices containing themixtures H2O:CO2:CH4 (10:1:1) and H2O:CO2:CH4:NH3 (10:1:1:1) at temperatures around 80 Kmonitored by infrared spectroscopy obtained at GANIL ion accelerator at France. Here, the mainobjective is to investigat…
Protoplanetary disks host simple and complex molecules in the gas phase and in the condensed state, from which new planets are formed. The formation and survival of these molecules is affected by the temperature and the UV and X-ray radiation field in the disk. To address these questions, laboratory and theoretical efforts are essential to determine where molecular species are destroyed o…
Enceladus and Europa are among the most interesting places in the Solar System. In the vicinity of giant planets, these moons are exposed to energetic ions and electrons, as well as UV radiation from the Sun. The surface temperatures of those two moons range from 60 to 120 K, and their composition is dominated by water ice together with other minor compounds. For the Jovian moon Europa, o…
