Record #172204:

Crystalline water ice on the Kuiper belt object (50000) Quaoar / David C. Jewitt, Jane Luu.

Title: Crystalline water ice on the Kuiper belt object (50000) Quaoar / David C. Jewitt, Jane Luu.
Author(s): Jewitt, David C.
Luu, Jane.
Date: 2004.
In: Nature. (2004.), Vol. 432(7018) (2004)
Abstract: Describes observation of crystalline ice on surface of Quaoar in Kuiper belt beyond Neptune using CISOO spectrometer at Subaru 8-metre telescope. Presents near-infrared reflection spectrum and compares with those of water-ice and of surfaces of Pluto and Charon. Presence of crystalline water ice implies heating at some point to at least 110 K. Current temperature of ~50 K and destruction of crystalline water ice by energetic particle irradiation on timescale ~10⁷ yr implies recent resurfacing of Quaoar, either by impact exposure of previously shielded ice or by cryovolcanic outgassing.
