Title: Ion irradiation induced effects on airless bodies in the solar system
Date: Wednesday, January 25th, 2012
Time: 11:30
Venue: Villa Bazzoni

Abstract: Solid surfaces in the Solar System are made of refractories (silicates/carbons) and/or frozen gases (ices) and are continuously modified by several processes among which ion irradiation plays a relevant role. The study of the induced effects in different environments (often referred to as “space weathering”) has been based on laboratory simulations. Among many studied effects there are sputtering, ion implantation, structural and morphological alterations, and chemical synthesis of molecular species. Here I review some experimental results with a view to their relevance in changing the spectral color of irradiated surfaces and their chemical alteration.
