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… 

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

Optical and Infrared Reflectance Spectrum of Kuiper Belt Object 1996 TL66

We have obtained optical (0.4-0.8 μm) and near-infrared (1.0-2.5 μm) reflectance spectra of the Kuiper Belt object 1996 TL66. The spectra show no evidence for absorption features and are neutral

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.

Near-Infrared Spectroscopy of the Bright Kuiper Belt Object 2000 EB173

We have obtained a near-infrared spectrum of the bright Kuiper Belt object 2000 EB173; the spectrum appears featureless. The spectrum has a sufficient signal-to-noise ratio to rule out the 1.5 and

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



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

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

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.

Infrared and Raman spectra of polyatomic molecules

This present volume represents the continuation of a series on Molecular Spectra and Molecular Structure. Illustrations have been included to make the reader visualize clearly the significance and
