ar X iv : a st ro - p h / 06 01 61 8 v 1 2 6 Ja n 20 06 The Surface of 2003 EL 61 in the Near Infrared

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 μm wavelength range, and from the Keck telescope across the 1.4 to 2.4 μm wavelength range. The signature of crystalline water ice is clear and obvious in all data collected. Like the surface of many outer solar system bodies, the surface o...

We present high signal precision optical reflectance spectra of the large Kuiper belt objects 2005 FY9 and 2003 EL61. The spectrum of 2005 FY9 exhibits strong CH 4-ice bands. A comparison between the spectrum and a Hapke model indicates 1 Observer at the MMT Observatory. Observations reported here were obtained at the MMT Observatory, a joint facility of the University of Arizona and the Smiths...
