Abstract

Laboratory experiments are essential to support the interpretation of astronomical observations and space mission data. Here we present a new experimental setup to characterize in the Vis-MIR range in both reflection and transmission modes astrophysically-relevant frozen volatiles deposited at low temperature and exposed to ion bombardment.

Abstract

Highlights: [•] We irradiate Allende meteorite with 40keV ions to simulate asteroid space weathering. [•] VIS–NIR reflectance spectra show weak reddening and darkening with increasing dose. [•] Sputtering and amorphization of matrix olivine induce modifications of IR bands. [•] Carbonaceous component evolves towards a highly disordered amorphous carbon. [•] Spectral changes scale with elastic dose and correspond to ∼103–104 yrs in main belt. [Copyright &y& Elsevier]
