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. Methods. We analyze adaptive optics J/H/K imaging observations of Ceres performed at Keck II Observatory in September 2002 with an equivalent spatial resolution of∼50 km. The spectral behavior of the main geological features present on Ceres is compared with laboratory samples. Results. Ceres’ shape… 
Thermal rotational lightcurve of dwarf-planet (1) Ceres at 235 GHz with the Submillimeter Array
Context. Previously published measurements of the millimeter-wave thermal rotational lightcurve of dwarf-planet (1) Ceres show incompatible results, proposing peak-to-peak lightcurve amplitudes
Physical Properties of (2) Pallas
Short-term variability on the surface of (1) Ceres - A changing amount of water ice?
Context. The dwarf planet (1) Ceres ‐ next target of the NASA Dawn mission ‐ is the largest body in the asteroid main belt. Although several observations of this body have been performed so far, the
Constraints on Ceres' Internal Structure and Evolution From Its Shape and Gravity Measured by the Dawn Spacecraft
Ceres is the largest body in the asteroid belt with a radius of approximately 470 km. In part due to its large mass, Ceres more closely approaches hydrostatic equilibrium than major asteroids.
Astronomical studies of solar system bodies 2060 Chiron and 1 Ceres
In this thesis two separate projects are investigated, a stellar occultation by 2060 Chiron and rotationally resolved spectra of 1 Ceres. On 29 November 2011 UT, 2060 Chiron occulted a 14-mag star;

Radar Observations of Asteroids 1 Ceres, 2 Pallas, and 4 Vesta
Asteroids 1 Ceres, 2 Pallas, and 4 Vesta were observed with the 13-cm Arecibo radar and the 3.5-cm Goldstone radar during several apparitions between 1981 and 1995. These observations help to
