Asteroid infrared reflectances and compositional implications.
Abstract
The paper assesses the state of asteroid infrared reflectance measurements and discusses what they have contributed to our understanding of asteroidal surfaces. The data suggest that space weathering has not significantly affected the optical properties of the asteroids. Thus comparisons of asteroid reflectance spectra with unweathered meteorite and rock data is a valid procedure. The high 1.6 and 2.2 micron reflectances of a number of asteroids strongly suggest the presence of a metallic phase.
