Ceres' surface is characterized by dark materials, phyllosilicates, ammonium-bearing minerals, carbonates, water ice, and salts. In addition to a global presence of carbon-bearing chemistry, local concentration of aliphatic organics has been detected by Dawn mission. The mission, thanks to the data collected by the Italian instrument VIR, showed clear evidence of a high amount of aliphatic organic material on the surface of Ceres. This has raised new questions about the origin and preservation of this material, especially when considering its high estimated abundance. We started a series of laboratory studies on physicochemical evolution of organic material interacting with minerals thought to be present on Ceres. The goal is to understand the transformations induced on these samples by processing with ultraviolet radiation. | Titolo del convegno: | European Planetary Science Congress 2022 | Luogo del convegno: | Granada, Spain | Periodo del convegno: | 18-23 September 2022 | URI: | http://hdl.handle.net/20.500.12386/34344 | URL: | https://meetingorganizer.copernicus.org/EPSC2022/EPSC2022-580.html https://www.epsc2022.eu/ |
