Context. We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources brighterExpand
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,Expand
A low density of 0.8 g cm-3 for the Trojan binary asteroid 617 Patroclus
TLDR
It is reported that the components of 617 Patroclus move around the system's centre of mass, describing a roughly circular orbit, and a very low density is derived, suggesting that they could have been formed in the outer part of the Solar System. Expand
The catalogue of radial velocity standard stars for Gaia. I. Pre-launch release.
Individual and combined radial velocity measurements are presented for the 1420 standard star candidates. (2 data files).
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,Expand
Eclipsing binary Trojan asteroid Patroclus: Thermal inertia from Spitzer observations
We present mid-infrared (8-33 micron) observations of the binary L5-Trojan system (617) Patroclus-Menoetius before, during, and after two shadowing events, using the Infrared Spectrograph (IRS) onExpand
Main belt binary asteroidal systems with eccentric mutual orbits
Using 8m-10m class telescopes and their Adaptive Optics (AO) systems, we conducted a long-term adaptive optics campaign initiated in 2003 focusing on four binary asteroid systems: (130) Elektra,Expand
Gaia Data Release 2
Aims. The Radial Velocity Spectrometer (RVS) on board the ESA satellite mission Gaia has no calibration device. Therefore, the radial velocity zero point needs to be calibrated with stars that areExpand
Main belt binary asteroidal systems with circular mutual orbits
In 2003, we initiated a long-term adaptive optics campaign to study the orbit of various main-belt asteroidal systems. Here we present a consistent solution for the mutual orbits of four binaryExpand
Near-Infrared Mapping and Physical Properties of the Dwarf-Planet Ceres
Aims. We study the physical characteristics (shape, dimensions, spin axis direction, albedo maps, mineralogy) of the dwarf-planet Ceres based on high-angular resolution near-infrared observations.Expand
