Photometric Observations Constraining the Size, Shape, and Albedo of 2003 EL61, a Rapidly Rotating, Pluto-sized Object in the Kuiper Belt
We present measurements at optical wavelengths of the spectral reflectance, rotational light curve, and solar phase curve of 2003 EL61. With apparent visual magnitude 17.5 at 51 AU from the Sun, thisExpand
A collisional family of icy objects in the Kuiper belt
TLDR
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 SURFACE OF 2003 EL61 IN THE NEAR-INFRARED
We report the detection of crystalline water ice on the surface of 2003 EL_(61). Reflectance spectra were collected from the Gemini North telescope in the 1.0 to 2.4 μm wavelength range and from theExpand
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
Methane and ethane on the bright Kuiper Belt object 2005 FY9
The spectrum of the bright Kuiper Belt object 2005 FY9 from 0.34 to 2.5μm is dominated by the red coloring of many outer solar system objects in the optical wavelength regime and by absorption due toExpand
Water ice on the satellite of kuiper belt object 2003 el61
We have obtained a near-infrared spectrum of the brightest satellite of the large Kuiper Belt object 2003 EL_(61). The spectrum has absorption features at 1.5 and 2.0 μm, indicating that water ice isExpand
Surface Properties of Kuiper Belt Objects and Centaurs
The outer solar system is inhabited by a population of small solar system bodies called Kuiper belt Objects (KBOs) and Centaurs. I present a survey of visible and near infrared (NIR) spectra of theExpand
