The 1.42- to 2.40-micrometer spectrum of Kuiper belt object 1993SC was measured at the Keck Observatory in October 1996. It shows a strongly red continuum reflectance and several prominent infrared absorption features. The strongest absorptions in 1993SC's spectrum occur near 1.62, 1.79, 1.95, 2.20, and 2.32 micrometers in wavelength. Features near the same wavelengths in the spectra of Pluto and Neptune's satellite Triton are due to CH4 on their surfaces, suggesting the presence of a simple… 
Spectrophotometry of Four Kuiper Belt Objects with NICMOS
We have obtained spectrophotometric observations of four Kuiper Belt objects using the Hubble Space Telescope's Near Infrared Camera and Multi-Object Spectrometer, NICMOS, in broad and medium
Identification of water ice on the Centaur 1997 CU26.
The reflectance spectrum of 1997 CU26 is matched by the spectrum of a mixture of low-temperature, particulate water ice and spectrally featureless but otherwise red-colored material, indicating different origins, thermal histories, or both for these two objects.
VR Photometry of Sixteen Kuiper Belt Objects
Abstract We present V and R photometry of 16 Kuiper belt objects (KBOs) from the 3.6-m Telescopio Nazionale Galileo and the Complejo Astronomico El Leoncito 2.1-m telescope. We find a wide dispersion
Detection of Water Ice on the Centaur 1997 CU_(26)
We report the detection of the 1.5 and 2.0 μm absorption bands due to water ice in the near-infrared reflection spectrum of the Centaur 1997 CU26, which is currently located just outside the
Spectrophotometric Observations of Edgeworth–Kuiper Belt Objects
Abstract The Edgeworth–Kuiper Belt (EKB) objects are fossil remnants of the formation of the Solar System and they represent an important reservoir of primordial, thermally unprocessed material. The
Visible and Infrared Photometry of Fourteen Kuiper Belt Objects
Abstract We present V–J colors of 14 Kuiper Belt objects using new infrared (J) data combined, in most cases, with simultaneous visible (V) data. We confirm the V–J vs absolute magnitude relation
Infrared spectroscopy of the largest known trans-neptunian object 2001 KX76
We report complete near-infrared (0.9-2.4 $\mu$m) spectral observations of the largest know trans-neptunian objects (TNO) 28976 = 2001 KX$_{76}$ taken in two different nights using the new Near
Light curves of the trans-Neptunian objects 1996 TP66 and 1994 VK8
AbstractWe have obtained a number of CCD images of two trans-Neptunian objects, 1994 VK8 and 1996 TP66, over two nights. The changes in magnitude of these objects have been examined, in a search for
Colors and Spectra of Kuiper Belt Objects
We present new measurements of the optical colors of Kuiper belt objects, principally from the Keck 10 m telescope. The measurements confirm the existence of a wide spread in the B-V, V-R, and R-I


Surface Ices and the Atmospheric Composition of Pluto
Observations of the 1.4- to 2.4-micrometer spectrum of Pluto reveal absorptions of carbon monoxide and nitrogen ices and confirm the presence of solid methane. Frozen nitrogen is more abundant than
Infrared spectroscopy of Triton and Pluto ice analogs: the case for saturated hydrocarbons.
It is shown that excess absorption in the surface spectra of Triton and Pluto, i.e., absorption not explained by present models incorporating molecules already identified on these bodies, may be due to alkanes (C(n)H2n+2) and related molecules frozen in the nitrogen.
The Origin of Short-Period Comets
The key results of an extensive series of numerical simulations of the evolution of comet orbits due to the gravitational perturbations of the giant planets are presented. The results show that the
Ices on the Surface of Triton
The near-infrared spectrum of Triton reveals ices of nitrogen, methane, carbon monoxide, and carbon dioxide, of which nitrogen is the dominant component, which challenges existing models of methane and nitrogen photochemistry on Tritons.
Tholins: organic chemistry of interstellar grains and gas
A complex organic solid produced from cosmically abundant molecules helps to explain many properties of the interstellar grains and gas.
The slow-moving objects 1993 SB and 1993 SC.
Abstract The results are reported of a search that was carried out in September 1993 for slow moving objects in the Solar System that may be potential members of the Kuiper belt of comets. Two
