Descripción
10199 Chariklo is the largest Centaur so far known. To investigate its
surface composition and possible surface variations, spectroscopic
observations have been carried out at the largest available telescopes.
We obtained near-infrared spectra at ESO-VLT (Cerro Paranal, Chile) and
TNG (La Palma, Spain) on April 2001 and March 2002, respectively.
Considering all the available data from 0.38 micron to 2.45 micron we
modeled the surface composition using geographical mixtures of different
materials. A tentative model, composed by a mixture of amorphous carbon,
titan tholins, olivines and some percentage of water ice, will be
presented and discussed.
