Centaur 10199 Chariklo (NIRSpec Reflectance Spectrum) [1]

Centaur 10199 Chariklo (NIRSpec Reflectance Spectrum)

Graphic titled “Centaur 10199 Chariklo: Surface Composition; NIRSpec PRISM.” The graphic shows a reflectance spectrum in the form of a graph of the Brightness of Light (relative reflectance) on the vertical y-axis versus Wavelength of Light in microns on the horizontal x-axis.

Graph

Axes

The y-axis showing relative reflectance ranges from dimmer (less light reflected) at the bottom to brighter (more light reflected) at the top. There are no labeled tick marks.

The x-axis ranges from 0.6 microns on the origin on the left to 4.1 microns on the right, with labeled tick marks every micron, starting at 1 micron.

Data

The spectrum is plotted as a continuous white line without individual data points or error bars. The line is jagged, indicating slight variations in relative reflectance with wavelength (i.e., from point to point along the x-axis). The broad shape of the line is curvy, with several prominent peaks and valleys. The reflectance increases between 0.7 and 2.6 microns (the line trends upward toward the right at an angle of about 45 degrees), with two relatively shallow dips around 1.6 and 2 microns. It then drops sharply between about 2.6 and 3.1 microns before increasing again to another peak at about 3.6 microns.

All three prominent valleys are highlighted in blue and labeled “Water Ice, H 2 O.”

Background

In the background of the graphic is an illustration of Chariklo and its rings, as seen from an oblique angle.
