Title: Correlating Color and Composition in the Kuiper Belt

Abstract: We propose to obtain colors and variability studies for 30 Kuiper Belt binaries to identify relationships between color and bulk physical properties: mass, albedo and density. We will also identify any binaries that have large amplitude variation indicative of non-spherical shapes or rapid rotation. In the Kuiper Belt, there is growing evidence that the very broad range of colors may reflect primordial bulk properties of Kuiper Belt objects rather than simply a veneer of altered materials. Kuiper Belt binaries are the only subset of Kuiper Belt objects for which masses are available. The correlation of color with physical properties opens a path to understanding the radial stratification of the protoplanetary disk and provides a link to disks around other stars.
