Water Ice on the Satellite of Kuiper Belt Object 2003 EL61
K. M Barkume, M. E. Brown, E. L. Schaller
We have obtained a near infrared spectrum of the brightest satellite of the large Kuiper Belt Object, 2003 EL61. The spectrum has absorption features at 1.5 and 2.0 microns, indica…
The Surface of 2003EL61 in the Near Infrared
C. A. Trujillo, M. E. Brown, K. M. Barkume +2
We report the detection of crystalline water ice on the surface of 2003 EL61. Reflectance spectra were collected from Gemini North telescope from 1.0 to 2.4 micron wavelength range…
Photometric Observations Constraining the Size, Shape, and Albedo of 2003 El61, a Rapidly Rotating, Pluto-Sized Object in the Kuiper Belt
David L. Rabinowitz, Kristina Barkume, Michael E. Brown +4
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…
