Proposal Title: Radar and Visible/Near-Infrared Investigation of Primitive Main-Belt Asteroids
ABSTRACT:
We propose to carry out continuous-wave radar observations of 25 main-belt asteroids in the highly primitive P and
D taxonomic classes. Such targets have been underrepresented in earlier radar surveys due to their relatively large
heliocentric distances. Observations will be carried out in four blocks during October 2004, January 2005, October
2005, and November-December 2005. We propose to coordinate the radar observations with nearly simultaneous
visible and near-infrared spectral observations in order to compare radar features with spectral features, with
particular emphasis on correlated or anticorrelated rotational variations in these features. The combined dataset
will constrain the near-surface roughness, composition, porosity, and hydration state of these dark, primitive,
potentially organic-rich objects, and could also reveal any spatial variations in these properties across the targets'
surfaces.
