The nonsolar abundance ratios of Arcturus deduced from spectrum synthesis
Using opacity distribution functions based on a newly expanded atomic and molecular line list, we have calculated a model atmosphere for Arcturus that reproduces the observed flux distribution.Expand
The Composition of Centaur 5145 Pholus
Abstract We present a new spectrum of the Centaur object 5145 Pholus between 1.15 and 2.4 μm. We model this, and the previously published (0.4- to 1.0-μm) spectrum, using Hapke scattering theory.Expand
Using new laboratory spectra, we have calculated the real and imaginary parts of the index of refraction of amorphous and crystalline H2O-ice from 20-150 K in the wavelength range 2.5-22 μm (4000-455Expand
Galaxy velocity dispersions using a cross-correlation method
A cross-correlation method for measuring velocity dispersions, introduced by Tonry and Davis (1979) and used for measuring velocity dispersions for 350 elliptical galaxies, is modified. The resultingExpand
The surface composition of Iapetus: Mapping results from Cassini VIMS
Abstract Cassini VIMS has obtained spatially resolved imaging spectroscopy data on numerous satellites of Saturn. A very close fly-by of Iapetus on September 10, 2007 provided the best data on theExpand
Optical constants of amorphous and crystalline H2O-ice in the near infrared from 1.1 to 2.6 μm
Abstract Using new laboratory spectra, we have calculated the real and imaginary parts of the index of refraction of amorphous and crystalline H 2 O-ice from 20 to 150 K in the frequency rangeExpand
Comparison between the Shkuratov and Hapke scattering theories for solid planetary surfaces: Application to the surface composition of two Centaurs
This project examines the different approaches which deal with the theory of radiative transfer on atmosphereless bodies. We present the relative merits of two scattering theories based on theExpand
Correlations between Line Strengths and Fine Structure in Elliptical Galaxies
Les correlations entre les forces des raies, Hβ, CN et (Mg I + MgH), et la structure fine sont analysees pour 36 galaxies elliptiques geantes. Les resultats sont utilises pour estimer lesExpand
Is Sedna another Triton
Sedna is, so far, the largest and most distant trans-neptunian object. It was observed at visible and near-infrared wavelengths using simultaneously two 8.2 m telescopes at the Very Large TelescopeExpand
A spectroscopic study of the surfaces of Saturn's large satellites: H 2 O ice, tholins, and minor constituents
Abstract We present spectra of Saturn's icy satellites Mimas, Enceladus, Tethys, Dione, Rhea, and Hyperion, 1.0–2.5 μm, with data extending to shorter (Mimas and Enceladus) and longer (Rhea andExpand
