The temperature‐dependent near‐infrared absorption spectrum of hexagonal H2O ice
Transmission spectra were measured between 1.0 and 2.7 μm for monocrystalline samples of hexagonal water ice at temperatures between 20 and 270 K. Samples were crystallized from liquid water withinExpand
Relative proper motions and the stellar velocity dispersion of the open cluster M67
Relative proper motions for 663 stars in the field of the old open cluster M67 have been determined using 44 Yerkes 40-in refractor plates. The resulting proper-motion marginal distributions haveExpand
Evidence for two populations of classical transneptunian objects : The strong inclination dependence of classical binaries
Abstract We have searched 101 Classical transneptunian objects for companions with the Hubble Space Telescope. Of these, at least 21 are binary. The heliocentric inclinations of the objects weExpand
High albedos of low inclination Classical Kuiper belt objects
Abstract We present observations of thermal emission from fifteen transneptunian objects (TNOs) made using the Spitzer Space Telescope . Thirteen of the targets are members of the ClassicalExpand
The Pluto system: Initial results from its exploration by New Horizons
TLDR
The New Horizons encounter revealed that Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface-atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes. Expand
Masses of Nix and Hydra
A four-body orbit solution for the Pluto system yields GM values of 870.3 ± 3.7, 101.4 ± 2.8, 0.039 ± 0.034, and 0.021 ± 0.042 km3 s−2 for Pluto, Charon, Nix, and Hydra, respectively. Assuming aExpand
Orbits and Photometry of Pluto's Satellites: Charon, S/2005 P1, and S/2005 P2
We present new astrometry of Pluto's three satellites from images taken of the Pluto system during 2002-2003 with the High Resolution Camera mode of the Advanced Camera for Surveys instrument on theExpand
Optical Properties of Ices From UV to Infrared
Remote sensing of ices at the surfaces and in the atmospheres of system solar objects are the subject of increasing studies in the UV, visible and infrared ranges. The spectro-imagers andExpand
Diverse albedos of small trans-neptunian objects
Discovery of trans-neptunian object (TNO) satellites and determination of their orbits has recently enabled estimation of the size and albedo of several small TNOs, extending the size range ofExpand
Surface compositions across Pluto and Charon
TLDR
The New Horizons team presents the complex surface features and geology of Pluto and its large moon Charon, including evidence of tectonics, glacial flow, and possible cryovolcanoes, as well as their analysis of the encounter data downloaded so far. Expand
