Abstract

We compare 13 near-infrared (0.8–2.4μm) spectra of two low albedo C complex outer-belt asteroid families: Themis and Veritas. The disruption ages of these two families lie at opposite extremes: 2.5±1.0Gyr and 8.7±1.7Myr, respectively. We found striking differences between the two families, which show a range of spectral shapes and slopes. The seven Themis family members (older surfaces) have “red” (positive) slopes in the 1.6–2.4μm region; in contrast, the six Veritas members (younger surfaces) have significantly “flatter” slopes at these same wavelengths
