A refined “standard” thermal model for asteroids based on observations of 1 Ceres and 2 Pallas
Abstract We present ground-based thermal infrared observations of asteroids 1 Ceres and 2 Pallas made over a period of 2 years. By analysing these data in light of the recently determined occultationExpand
Io's heat flow from infrared radiometry: 1983–1993
We report the following results from a decade of infrared radiometry of Io: (1) The average global heat flow is more than ∼2.5 W m−2, (2) large warm (≤200 K) volcanic regions dominate the global heatExpand
Radiometry of near-earth asteroids.
Thermal models are used to derive radiometric albedos and diameters for 22 Aten, Apollo, and Amor asteroids, finding several of these asteroids appear to have surfaces of relatively high thermal inertia due to the exposure of bare rock or a coarse regolith. Expand
Iapetus’ geophysics : rotation rate, shape, and equatorial ridge
Iapetus has preserved evidence that constrains the modeling of its geophysical history from the time of its accretion until now. The evidence is (a) its present 79.33-day rotation or spin rate, (b)Expand
26Al decay: Heat production and a revised age for Iapetus
Abstract We revisit the appropriate energies to be used for computing heat production from 26Al decay. Due to the complexity of the decay scheme of this radioisotope, previous geophysical studiesExpand
Hydrogen peroxide on the surface of Europa.
Spatially resolved infrared and ultraviolet wavelength spectra of Europa's leading, anti-jovian quadrant observed from the Galileo spacecraft show absorption features resulting from hydrogen peroxide, demonstrating that Europa's surface chemistry is dominated by radiolysis. Expand
The Cassini Visual And Infrared Mapping Spectrometer (Vims) Investigation
The Cassini visual and infrared mapping spectrometer (VIMS) investigation is a multidisciplinary study of the Saturnian system. Visual and near-infrared imaging spectroscopy and high-speedExpand
Composition and Physical Properties of Enceladus' Surface
Observations of Saturn's satellite Enceladus using Cassini's Visual and Infrared Mapping Spectrometer instrument were obtained during three flybys in 2005, and upper limits of 140 kelvin are derived for the temperatures in the tiger stripes. Expand
An overview of the descent and landing of the Huygens probe on Titan
An overview of the Huygens mission is reported, which enabled studies of the atmosphere and surface, including in situ sampling of the organic chemistry, and revealed an Earth-like landscape. Expand
A Three-Parameter Asteroid Taxonomy
Broadband U, V, and x photometry together with IRAS asteroid albedos have been used to construct an asteroid classification system. The system is based on three parameters (U-V and v-x color indicesExpand
