We report the detection of water ice in the Centaur 2060 Chiron, based on near-infrared spectra (1.0-2.5 µm) taken with the 3.8 m United Kingdom Infrared Telescope and the 10 m Keck Telescope. The appearance of this ice is correlated with the recent decline in Chiron's cometary activity: the decrease in the coma cross section allows previously hidden solid-state surface features to be seen. We predict that water ice is ubiquitous among Centaurs and Kuiper Belt objects, but its surface coverage…

Near-Infrared Spectra of Centaurs and Kuiper Belt Objects
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
Spectrophotometry of Kuiper Belt Objects 20000 Varuna, 2000 Eb 173 and Centaur 10199 Chariklo
Due to the distance, faintness, and very recent discovery of Kuiper Belt Objects (KBOs) and Centaurs, very little is known about the physical characteristics of these basic building blocks of the
Water ice on the surface of the large TNO 2004 DW
We have obtained visible and near infrared spectra of the Trans Neptunian object 2004 DW, a few days after its discovery, at the Telescopio Nazionale Galileo (TNG). 2004 DW belongs to the plutino
Physical Properties of Trojan and Centaur Asteroids
Trojan and Centaurs are primitinve, peculiar objects orbiting in the middle solar system. Both groups characteristically have low albedos and red colors. Physical observations of Trojans reveal
Colours and Composition of the Centaurs
Centaurs are widely believed to come from the Edgeworth-Kuiper belt, located beyond the orbit of Neptune. From here they can be injected into the inner part of the Solar System through planetary
The Near Infrared Spectrum of Miranda: Evidence of Crystalline Water Ice
A spectrum from 1.2 to 2.5 μm of Uranus' small satellite Miranda obtained in June 1999 reveals strong water-ice signatures. It confirms the existence of a 2.0-μm water feature previously detected on
The Ices on Transneptunian Objects and Centaurs
Transneptunian objects (TNOs) and Centaurs are small bodies orbiting the Sun in the cold outer regions of the Solar System. TNOs include Pluto and its satellite Charon, and Neptune’s large satellite
Centaurs are believed to be Kuiper Belt objects in transition between Jupiter and Neptune before possibly becoming Jupiter family comets. Some indirect observational evidence is consistent with the
Characterization of material around the centaur (2060) Chiron from a visible and near-infrared stellar occultation in 2011
The centaur (2060) Chiron exhibits outgassing behaviour and possibly hosts a ring system. On 2011 November 29, Chiron occulted a fairly bright star (R ∼ 15 mag) as observed from the 3-m NASA


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 CU_(26), which is currently located just outside 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
Cometary activity in 2060 Chiron
Results of a 2-yr (1988-90) investigation of cometary activity in 2060 Chiron based on CCD photometry and spectroscopy are reported. The photometry observations include a new rotational light curve

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.
Stellar Occultation by 2060 Chiron
Abstract A 14th magnitude double star was occulted by 2060 Chiron on 1993 November 7. Observations of this event were obtained from five locations in California. An occultation by Chiron's nucleus
The color temperature of (2060) Chiron: A warm and small nucleus
We present three sets of thermal-infrared observations of (2060) Chiron, obtained in 1991, 1993, and 1994. These observations allow the first estimates of the color temperature of Chiron as well as
Optical and infrared observations of the Centaur 1997 CU26
Minor planet 1997 CU26 is a Centaur, and is probably undergoing dynamical evolution inwards from the Kuiper Belt. We present optical and infrared (VRIJHK) photometry which gives mean colours of V - R
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
