Emissivity and reflectance spectra of sulfide-bearing samples: new constraints for the hermean surface composition.
Abstract
Mercury is an extreme planet with the largest temperature excursion in the Solar System that may affect spectral properties of the surface. Evidences suggest plagioclase, pyroxene, and olivine, with lesser amounts of quartz as possible mineralogy of Mercury's surface. Furthermore, the presence of abundant sulfide in hollows has been proposed. Here, we measure the emissivity and reflectance of mixtures composed of a silicate and a sulfide component at different temperatures.
