Report of the IAU/IAG Working Group on cartographic coordinates and rotational elements: 2006
Every three years the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements revises tables giving the directions of the poles of rotation and the prime meridians of the planets,…
Properties of the 67P/Churyumov-Gerasimenko interior revealed by CONSERT radar
Measurements of the interior of Comet 67P/Churyumov-Gerasimenko by Radiowave Transmission (CONSERT) suggest the upper part of the “head” of 67P is fairly homogeneous on a spatial scale of tens of meters, and the dust component may be comparable to that of carbonaceous chondrites.
Report of the IAU Working Group on Cartographic Coordinates and Rotational Elements: 2009
Every three years the IAU Working Group on Cartographic Coordinates and Rotational Elements revises tables giving the directions of the poles of rotation and the prime meridians of the planets,…
Subsurface Radar Sounding of the South Polar Layered Deposits of Mars
The ice-rich south polar layered deposits of Mars were probed with the Mars Advanced Radar for Subsurface and Ionospheric Sounding on the Mars Express orbiter, suggesting a composition of nearly pure water ice.
Report of the IAU Working Group on Cartographic Coordinates and Rotational Elements: 2015
This report continues the practice where the IAU Working Group on Cartographic Coordinates and Rotational Elements revises recommendations regarding those topics for the planets, satellites, minor planets, and comets approximately every 3 years, and recommends that planning and efforts be made to make controlled cartographic products.
Resistance to the Motion of a Small Sphere Moving Through a Gas
The Comet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT): A Short Description of the Instrument and of the Commissioning Stages
The primary scientific goal of the CONSERT experiment on the Rosetta space mission is to investigate the deep interior of the nucleus of comet 67/P Churyumov-Gerasimenko. This will be achieved…
A spectroscopic survey of D-type asteroids
We present CCD spectra of 19 asteroids previously classified as D-type covering the wavelength range 3500≤λ≤9600 A. A comparison with previously published photometric data shows excellent agreement.…
