Figure 3: The Relationship Between the Depth of Absorption and the Peak Wavelength of the Deepest (IMAGE)
Caption
The relationship between the depth of absorption and the peak wavelength of the deepest absorption for the feature at around 2.7 micrometers in C-type asteroids (shown by the green arrows in figure 2). The different marks show differences of subgroups in the types of C-type asteroids (based on the Bus-DeMeo taxonomic classification). The trend of 13 asteroids from top right to bottom left indicated by the arrow can be understood in terms of the dehydration process. Four asteroids with the thin red symbols deviate from the general trend. A further follow-up investigation is required for understanding the nature of these outliers.
