Data pubblicazione: | 2021 | Titolo del volume in cui è pubblicato il poster: | Europlanet Science Congress 2021 | Abstract: | Ceres is the largest object in the Solar System main belt. Clearly, Ceres experienced extensive water-related processes and geochemical differentiation and nowadays it is a body with a complex geological and chemical history. Its 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. In this context, we have started a series of laboratory spectroscopy measurements targeted to study the physicochemical interactions between organic material and minerals possibly present on Ceres. The goal is to understand the transformations induced on these samples by ultraviolet radiation, neutral atoms, and fast ions, under experimental conditions that simulate the environment of Ceres. The spectroscopic data obtained in laboratory experiments allow, through the comparison with the observations of the VIR spectrometer aboard the Dawn mission, to clarify the nature and origin of organic material identified on Ceres. | Titolo del convegno: | Europlanet Science Congress 2021 | Luogo del convegno: | Virtual meeting | Periodo del convegno: | 13 – 24 September, 2021 | URI: | http://hdl.handle.net/20.500.12386/35165 | URL: | https://www.epsc2021.eu/ | Fulltext: | open |
