We have measured the optical and infrared colors of five Kuiper belt objects to search for evidence of spectral diversity among these bodies. We find extreme differences, especially in the measured V - J color indices, that indicate a wide range of surface compositions in the Kuiper belt.

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

U-Band Photometry of Kuiper Belt Objects

We present U-band photometry of Kuiper Belt objects taken to further investigate their color-orbit systematics. As at longer optical and near-infrared wavelengths, the U-band colors of Kuiper Belt

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

Near-Infrared Color Properties of Kuiper Belt Objects and Centaurs: Final Results from the ESO Large Program

We present near-IR JHK broadband photometry for 17 Kuiper Belt objects (KBOs) and Centaurs. The observations were performed within the ESO Large Program on the "Physical Properties of Kuiper Belt

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

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

An Optical Survey of the Active Centaur C/NEAT (2001 T4)

We present the results of optical observations of C/NEAT (2001 T4) taken on three dates between 2001 October and 2002 September at the University of Hawaii 2.2 m telescope. Coma was present for each


▪ Abstract The region of the solar system immediately beyond Neptune's orbit is densely populated with small bodies. This region, known as the Kuiper Belt, consists of objects that may predate Nept...

Detection of Water Ice on 2060 Chiron

Abstract We present a reflectance spectrum of 2060 Chiron over the wavelength range 1.6–2.2 μm. The 2-μm water ice absorption feature seen in several other Centaurs at λ=2.03 μm is identified at the



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

Near-Infrared Photometry and Spectroscopy of the Unusual Minor Planet 5145 Pholus (1992AD)

Abstract We present near-infrared photometry which confirms that asteroid 5145 Pholus has unusually red visual to infrared colors. Its near-infrared spectrum exhibits structure between 1.8 and 2.4 μm

Infrared (JHK) photometry of asteroids. II

JHK (1.2, 1.6, and 2.2 micron) photometry for 38 asteroids of various spectral classifications is reported. M asteroids tend to have infrared colors intermediate between the color domains of E and P

Surface composition of Kuiper belt object 1993SC.

The 1.42- to 2.40-micrometer spectrum of Kuiper belt object 1993SC shows a strongly red continuum reflectance and several prominent infrared absorption features, suggesting the presence of a simple hydrocarbon ice or more complex hydrocarbons on 1993SC.

Optical and Infrared Photometry of Kuiper Belt Object 1993SC

Abstract Minor planet 1993SC, with a semi-major axis of 39.67 AU, is one of the brightest of numerous recently discovered objects with orbits close to or beyond Neptune. It is a member of the Kuiper

Surface reflectance properties of distant Solar system bodies

The recent discoveries of over 40 new objects with orbits beyond 30 au represent the first sampling of a reservoir of objects lying beyond Neptune, known as the Kuiper Belt (or Edgeworth-Kuiper

Absolute calibration of photometry at 1 through 5 microns

The solar-analog method is used to determine the absolute calibration of photometry in the J, H, K, L, and M bands to an accuracy of 3 percent, (5 percent at M). This calibration agrees well with the

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
