Title: Near-IR photometry of KBOs and Centaurs in support of Spitzer space telescope data

Abstract: The objective of this proposal is to measure near-infrared broadband colors of Centaurs and Kuiper Belt objects (KBOs). The proposed ground- based observations will support 3.6 and 4.5 (micron) photometry of these bodies obtained with the Infrared Array Camera (IRAC) on the Spitzer space telescope. Extending reflectances past 2.5 (micron) with Spitzer enables sensitive searches for absorptions in the 3- to 5-(micron) region, where relevant species (e.g., organics, H_2O, CO_2, CH_4, hydrated silicates) have their fundamental absorption bands. In order to assess the presence of absorptions, however, the Spitzer photometry must be tied to shorter wavelength near-infrared reflectances.
