We evaluated possible parent bodies for both meteorites by comparing their VNIR spectra (before and after irradiation) with those of ∼400 main-belt asteroids.

For Eagle we observe little spectral variation, and therefore we do not expect to observe a significant spectral difference between EC meteorites and their parent bodies. La variation compositionnelle des petits corpsa travers le syteme. For Vaca Muerta we observe a reddening and darkening of the reflectance spectrum with progressive irradiation, consistent with what is observed in the cases of silicates and silicate-rich meteorites such as OCs and HEDs. (2009), is based on reflectance spectrum characteristics for 371 asteroids measured over the wavelength 0.45 to 2.45 microns. urn:nasa:pds::document:taxocard::1.0 /document/taxocard.xml urn:nasa:pds::document:taxocard::1.0 /document/taxocard.pdf.

These experiments were performed with the aims of (a) quantifying the spectral effect of the solar wind on their parent asteroid surfaces and (b) identifying their parent bodies within the asteroid belt. The Bus-DeMeo asteroid taxonomy classification system, described in DeMeo et al. Darby Asteroids are currently classified by the shapes of their reflectance spectra in the visible and near-infrared wavelength regions using the Bus-DeMeo taxonomy. We present new irradiation experiments performed on the enstatite chondrite Eagle (EL6) and the mesosiderite Vaca Muerta.
