    Abstract

    We find a clear diversity in the 3 pm and 10 pm features of three Cybele asteroids: (107) Camilla, (121) Hermione, and (65) Cybele. (121) Hermione exhibits a "check-like" 3 mu m feature, which may be attributed to OH-dominated minerals and (107) Camilla shows a rounded "bowl" like feature closer to that of (65) Cybele, which may be attributed to H2O-dominated minerals. The 10 pm features of these three asteroids are also different from each other. (C) 2012 Elsevier Inc. All rights reserved.
