We present high signal precision optical reflectance spectra of the large Kuiper Belt objects 2005 FY9 and 2003 EL61. The spectrum of 2005 FY9 exhibits strong CH4 ice bands. A comparison between the spectrum and a Hapke model indicates that the CH4 bands are shifted 3.25 ± 2.25 A relative to pure CH4 ice, suggesting the presence of another ice component on the surface of 2005 FY9, possibly N2 ice, CO ice, or Ar. The spectrum of 2003 EL61 is remarkably featureless. There is a hint of an O2 ice…

Evidence of N 2-Ice On the Surface of the Icy Dwarf Planet 136472 ( 2005 FY 9 )
We present high signal precision optical reflectance spectra of 2005 FY9 taken with the Red Channel Spectrograph and the 6.5-m MMT telescope on 2006 March 4 UT (5000−9500 Å; 6.33 Å pixel) and 2007
Interpretation of the Near-IR Spectra of the Kuiper Belt Object
Visible and near-IR observations of the Kuiper Belt Object (136472) 2005 FY(9) have indicated the presence of unusually long (1 cm or more) optical path lengths in a layer of methane ice. Using

We observed the 2600-3200 A (hereafter, mid-UV) reflectance of two Kuiper Belt Objects (KBOs), two KBO satellites, and a Centaur, using the Hubble Space Telescope (HST) Cosmic Origins Spectrograph
Time-Resolved Near-Infrared Photometry of Extreme Kuiper Belt Object Haumea
We present time-resolved near-infrared (J and H) photometry of the extreme Kuiper belt object (136108) Haumea (formerly 2003 EL61) taken to further investigate rotational variability of this object.
Comparative Kbology: Using Surface Spectra of Triton, Pluto, and Charon to Investigate Atmospheric, Surface, and Interior Processes on Kuiper Belt Objects
We present the results of an investigation to determine the longitudinal (zonal) distributions and temporal evolution of ices on the surface of Triton. Between 2002 and 2014, we obtained 63 nights of
Near-infrared spatially resolved spectroscopy of (136108) Haumea's multiple system
The transneptunian region of the solar system is populated by a wide variety of icy bodies showing great diversity. The dwarf planet (136108) Haumea is among the largest TNOs and displays a highly

Aims. We investigate the surface composition of the Plutino (47171) 1999 TC36. Methods. We completed near-infrared photometric and spectroscopic observations of (47171) 1999 TC36 with the adaptive
Surface Properties of Kuiper Belt Objects and Centaurs
The outer solar system is inhabited by a population of small solar system bodies called Kuiper belt Objects (KBOs) and Centaurs. I present a survey of visible and near infrared (NIR) spectra of the

Water Ice on Kuiper Belt Object 1996 TO66
The 1.40-2.45 μm spectrum of Kuiper Belt object 1996 TO66 was measured at the Keck Observatory in 1998 September. Its spectrum shows the strong absorptions near 1.5 and 2.0 μm that are characteristic

The spectrum of the bright Kuiper Belt object 2005 FY9 from 0.34 to 2.5μm is dominated by the red coloring of many outer solar system objects in the optical wavelength regime and by absorption due to

Crystalline water ice on the Kuiper belt object (50000) Quaoar
TLDR
It is concluded that Quaoar has been recently resurfaced, either by impact exposure of previously buried (shielded) ices or by cryovolcanic outgassing, or by a combination of these processes.
Distribution and Evolution of CH4, N2, and CO Ices on Pluto's Surface: 1995 to 1998
Abstract We present new near-infrared spectra of the planet Pluto obtained at Lowell Observatory on 83 nights during 1995–1998. The dense temporal sampling of our observations enables us to measure
