We have acquired near-infrared spectra of Kuiper Belt objects 2003 UZ117, 2005 CB79, and 2004 SB60 with NIRC on the Keck I telescope. These objects are dynamically close to the core of the 2003 EL61 collisional family and were suggested to be potential fragments of this collision by Ragozzine and Brown. We find that the spectra of 2003 UZ117 and 2005 CB79 both show the characteristic strong water ice absorption features seen exclusively on 2003 EL61, its largest satellite, and the six other…

We present a new near-infrared photometric system for detection of water ice and methane ice in the solar system. The system consists of two medium-band filters in the K-band region of the
Comparative Kbology: Using Surface Spectra of Triton, Pluto, and Charon to Investigate Atmospheric, Surface, and Interior Processes on Kuiper Belt Objects
We present the results of an investigation to determine the longitudinal (zonal) distributions and temporal evolution of ices on the surface of Triton. Between 2002 and 2014, we obtained 63 nights of
Size and albedo of Kuiper belt object 55636 from a stellar occultation
Observations of a multi-chord stellar occultation by KBO 55636, which occurred on 9 October 2009, find that it has a mean radius of 143 ± 5 km and a geometric albedo of in the V photometric band, which establishes that KBO55636 is smaller than previously thought and that, like its parent body, it is highly reflective.
The formation of Haumea and its family via binary merging
Dozens of families of asteroids in the asteroid belt have similar orbits and compositions because they formed through a collision. However, the icy debris beyond the orbit of Neptune, called the

Context. The trans-Neptunian region of the Solar System is populated by a wide variety of icy bodies showing great diversity in orbital behavior, size, surface color, and composition. One can also
“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 have
Rotational properties of the Haumea family members and candidates: Short-term variability
Haumea is one of the most interesting and intriguing trans-Neptunian objects (TNOs). It is a large, bright, fast rotator, and its spectrum indicates nearly pure water ice on the surface. It has at
Compositional Study of Trans-Neptunian Objects at λ > 2.2 μm
Using data from the Infrared Array Camera on the Spitzer Space Telescope, we present photometric observations of a sample of 100 trans-Neptunian objects (TNOs) beyond 2.2 μm. These observations,

Haumea is a dwarf planet with two known satellites, an unusually high spin rate, and a large collisional family, making it one of the most interesting objects in the outer solar system. A fully


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
Candidate Members and Age Estimate of the Family of Kuiper Belt Object 2003 EL61
The collisional family of Kuiper Belt object (KBO) 2003 EL61 opens the possibility for many interesting new studies of processes important in the formation and evolution of the outer solar system. As
Near-Infrared Spectroscopy of Centaurs and Irregular Satellites
We have obtained near-infrared spectra of the four brightest known Centaurs and of five irregular satellites of giant planets. Many of these objects show 1.5 and 2.0 μm absorption bands indicative of
