Water Ice in the Kuiper Belt

  author={Michael E. Brown and Emily L. Schaller and Wesley C. Fraser},
  journal={The Astronomical Journal},
We examine a large collection of low-resolution near-infrared spectra of Kuiper Belt objects (KBOs) and centaurs in an attempt to understand the presence of water ice in the Kuiper Belt. We find that water ice on the surface of these objects occurs in three separate manners: (1) Haumea family members uniquely show surfaces of nearly pure water ice, presumably a consequence of the fragmentation of the icy mantle of a larger differentiated proto-Haumea; (2) large objects with absolute magnitudes… Expand

Rotationally resolved spectroscopy of (20000) Varuna in the near-infrared
Models of the escape and retention of volatiles by minor icy objects exclude any presence of volatile ices on the surface of TNOs smaller than ~1000km in diameter at the typical temperature in thisExpand
Complex Water-ice Mixtures on NII Nereid: Constraints from NIR Reflectance
Nereid, Neptune’s third-largest satellite, lies in an irregular orbit and is the only outer satellite in the system (apart from Triton) that can be spectroscopically characterized with the currentExpand
Experimenting with Mixtures of Water Ice and Dust as Analogues for Icy Planetary Material
Due to its abundance and unique properties, water is a major actor in the formation and evolution of many planetary surfaces as well as a sensitive and reliable tracer of past geologic and climaticExpand
“TNOs are Cool”: A survey of the trans-Neptunian region
Context. A group of trans-Neptunian objects (TNOs) are dynamically related to the dwarf planet 136108 Haumea. Ten of them show strong indications of water ice on their surfaces, are assumed to haveExpand

Models of the Solar System's dynamical evolution predict the dispersal of primitive planetesimals from their formative regions among the gas-giant planets due to the early phases of planetaryExpand
Photometric Measurements of H2O Ice Crystallinity on Trans-Neptunian Objects
We present a measurement of H2O ice crystallinity on the surface of trans-neptunian objects (TNOs) with near-infrared narrow-band imaging. The newly developed photometric technique allows us toExpand
Phoebe: A Surface Dominated by Water
The Saturnian irregular satellite, Phoebe, can be broadly described as a water-rich rock. This object, which presumably originated from the same primordial population shared by the dynamicallyExpand
The 3-4 μm Spectra of Jupiter Trojan Asteroids
To date, reflectance spectra of Jupiter Trojan asteroids have revealed no distinctive absorption features. For this reason, the surface composition of these objects remains a subject of speculation.Expand
Trans-Neptunian objects and Centaurs at thermal wavelengths
Abstract The thermal emission of Trans-Neptunian objects and Centaurs has been observed at mid- and far-infrared wavelengths—with the biggest contributions coming from the Spitzer and Herschel spaceExpand
The Structure of the Distant Kuiper Belt in a Nice Model Scenario
This work explores the orbital distribution of minor bodies in the outer Solar System emplaced as a result of a Nice model migration from the simulations of Brasser & Morbidelli (2013). ThisExpand


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 wellExpand
Thermal evolution of Kuiper belt objects, with implications for cryovolcanism
Abstract We investigate the internal thermal evolution of Kuiper belt objects (KBOs), small (radii 2500 kg m − 3 ) bodies orbiting beyond Neptune, focusing on Pluto's moon Charon in particular. OurExpand
Near-Infrared Spectroscopy of Charon: Possible Evidence for Cryovolcanism on Kuiper Belt Objects
We present the first reported adaptive optics spectra of Charon in the H and K bands, which examine the anti-Pluto and sub-Pluto hemispheres. The ice temperature is estimated at 40-50 K, based on theExpand
A collisional family of icy objects in the Kuiper belt
The discovery of a family of Kuiper belt objects with surface properties and orbits that are nearly identical to those of 2003 EL61, which appears to be fragments of the ejected ice mantle of2003 EL61. Expand
The Compositions of Kuiper Belt Objects
Objects in the Kuiper belt are difficult to study in detail, even with the best telescopes available. Therefore, for many years, studies of the compositions of these objects were relegated toExpand
We present photometry and spectra of the large Kuiper belt object 2007 OR10. The data show significant near-infrared absorption features due to water ice. While most objects in the Kuiper belt withExpand
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 characteristicExpand
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. Expand
We propose a chemical and dynamical process to explain the surface colors of the Kuiper belt. In our hypothesis, the initial bulk compositions of the bodies themselves can be quite diverse—as is seenExpand
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-IExpand
