Fig. 2. A composite spectrum of 8405 Asbolus that includes visible data from 1998 by Barucci et al. (1999), and the near-infrared data reported in this paper. As on Fig. 1, the spectra in the J, H and K bands have been adjusted using the average V-J, V-H and V-K colors of Davies et al. (1998). The R and I mean relative reflectances (normalized to 1 at V) of Davies et al. are also shown, as well as the error bars on all Davies et al. (1998) reflectances. Two different models with spatial mixtures are presented. The albedo at 0.55 µm is 0.025 for the carbon+kerogen model, and 0.055 for the carbon+tholin+water ice model. Grain sizes are: 0.1 µm for amorphous carbon, 0.1 µm for tholins and 10 µm for water ice.
