After ion bombardment and UV photolysis the chemical composition and the structure of the sample is modified. Both more volatile and less volatile species are formed and if C-bearing species are present in the original sample a refractory residue is also formed. Here we present some laboratory experiments which show the formation of (complex) molecular species in ion irradiated simple ices and in the organic residues formed after warm up of the processed ices at room temperature. In particular it will be shown that complex organic species found in organic residues, could have contributed to provide the early Earth with the seeds from which life has initiated. | Titolo del convegno: | European Conference on Laboratory Astrophysics ECLA2020 | Luogo del convegno: | Anacapri, Italy | Periodo del convegno: | 26 September - 1 October, 2020 | URI: | http://hdl.handle.net/20.500.12386/34622 | URL: | https://api.elsevier.com/content/abstract/scopus_id/85172417669 https://link.springer.com/chapter/10.1007/978-3-031-29003-9_24#rightslink |
