Composition and Grain Sizes of Dark Material in Saturn's Icy Satellites and Rings
Abstract
Cassini VIMS has acquired spectra of spatially resolved icy satellites and the rings of Saturn for over 6 years. The VIMS data provide a mixture space of ice and contaminants. In particular, the close Rev 49 fly-by of Iapetus provided spectra of the purest patches of dark material in the Saturn system as well as mixtures with ice. We have studied the spectral properties of the icy satellites and rings, modeling both the ice grain size distribution, the dark contaminants and their grain sizes. Modeling included nano-phase to micron-sized and larger particles and the effects of diffraction and Rayleigh absorption. We find that a simple and consistent explanation for the dark material includes nano-phase metallic iron and iron oxides. Carbon and tholins may also be present but are not spectrally dominant. <P />...
