Title: | Astrobiology studies and extraterrestrial sample analysis at the Laboratory for Experimental Astrophysics - Catania | Authors: | PALUMBO, Maria Elisabetta Baratta, G. OCCHIPINTI, Giovanni Scirè Scappuzzo, C. STRAZZULLA, Giovanni |
Issue Date: | 2021 | Journal: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Volume: | 1st Italian Space Agency workshop on Astrobiology | Editors: | Negri, B.; Ammannito, E.; Pacelli, C. | Number: | 92 | First Page: | 158 | Abstract: | Energetic ions (galactic cosmic rays, solar wind, energetic solar ions) and UV photons are believed to significantly contribute to the evolution of solid matter in astrophysical environments. At the Laboratory for Experimental Astrophysics at INAF-Osservatorio Astrofisico di Catania samples are exposed to space conditions such as high vacuum, low temperature (15-300 K), UV irradiation (266 nm and Lyman-alpha at 121.6 nm) and fast ion bombardment (60-400 keV) and are analyzed in situ by Infrared and Raman spectroscopy. Ices, carbons and silicates have been processed and analyzed. In addition, extraterrestrial dust particles (e.g. IDPs, cometary dust particles, and meteorites) have been characterized by non destructive techniques such as micro-Raman and UV-Vis-IR spectroscopy. Furthermore, spectra of extraterrestrial samples have been compared to spectra of laboratory analogues. Here we present some of the most recent results relevant to Astrobiology and the ongoing upgrade of the experimental set-up. | Conference Name: | 1st Italian Space Agency workshop on Astrobiology | URI: | http://hdl.handle.net/20.500.12386/34459 | URL: | https://www.memsait.it/volumi/Vol.%2092%20-%20N.2%20-%202021.php | ISSN: | 0037-8720 | Bibcode ADS: | 2021MmSAI..92b.158P | Fulltext: | open |
