Abstract:
We present here an extensive survey of near-infrared (NIR) spectra of
Kuiper belt objects (KBOs) and Centaurs taken with the Keck I
Telescope. We find that most spectra in our sample are well
characterized by a combination of water ice and a featureless
continuum. A comparative analysis reveals that the NIR spectral
properties have little correlation to the visible colors or albedo,
with the exception of the fragment KBOs produced from the giant impact
on 2003 E
Description:
Low-resolution (λ/δλ∼160) spectra from 1.4 to
2.5um were obtained with NIRC for each object using a 150lines/um
grism and an H-K-order sorting filter.
