Spectral characteristics and modeling of the trans-neptunian object (55565) 2002 AW197 and the Centaurs (55576) 2002 GB10 and (83982) 2002 GO91: ESO Large Program on TNOs and Centaurs

Analysis of these visible-near infrared reflectance spectra with radiative transfer models are compatible with a surface composed of intimate mixtures of organics compounds (Triton tholins, amorphous carbon) and contaminated water ice, although other possibilities exist.
