Abstract To take full advantage of the September 2008 opposition passage of the M-type Asteroid (216) Kleopatra, we have used near-infrared adaptive optics (AO) imaging with the W.M. Keck II telescope to capture unprecedented high resolution images of this unusual asteroid. Our AO observations with the W.M. Keck II telescope, combined with Spitzer/IRS spectroscopic observations and past stellar occultations, confirm the value of its IRAS radiometric radius of 67.5 km as well as its dog-bone… Expand
Radar observations and shape model of asteroid 16 Psyche
Abstract Using the S-band radar at Arecibo Observatory, we observed 16 Psyche, the largest M-class asteroid in the main belt. We obtained 18 radar imaging and 6 continuous wave runs in November andExpand
Physical and dynamical properties of the main belt triple asteroid (87) Sylvia
We present the analysis of high angular resolution observations of the triple Asteroid (87) Sylvia collected with three 8-10 m class telescopes (Keck, VLT, Gemini North) and the Hubble SpaceExpand
Occultation evidence for a satellite of the Trojan asteroid (911) Agamemnon
Abstract On 2012 January 19, observers in the northeastern United States of America observed an occultation of 8.0-mag HIP 41337 star by the Jupiter–Trojan (911) Agamemnon, including one videoExpand
A revised shape model of asteroid (216) Kleopatra
Abstract We used three different sets of Arecibo delay-Doppler radar images and five well-covered occultations to generate a revised three-dimensional shape model of asteroid (216) Kleopatra with aExpand
The small binary asteroid (939) Isberga
In understanding the composition and internal structure of asteroids, their density is perhaps the most diagnostic quantity. We aim here at characterizing the surface composition, mutual orbit, size,Expand

Characteristics and large bulk density of the C-type main-belt triple asteroid (93) Minerva
From a set of adaptive optics (AO) observations collected with the W.M. Keck telescope between August and September 2009, we derived the orbital parameters of the most recently discovered satellitesExpand
Multiple asteroid systems: Dimensions and thermal properties from Spitzer Space Telescope and ground-based observations
We collected mid-IR spectra from 5.2 to 38 lm using the Spitzer Space Telescope Infrared Spectrograph of 28 asteroids representative of all established types of binary groups. Photometric lightcurvesExpand
Evidence of a metal-rich surface for the asteroid (16) Psyche from interferometric observations in the thermal infrared
Abstract We describe the first determination of thermal properties and size of the M-type Asteroid (16) Psyche from interferometric observations obtained with the Mid-Infrared InterferometricExpand
17 F eb 2 01 5 Asteroid Models from Multiple Data Sources
In the past decade, hundreds of asteroid shape models have be en derived using the lightcurve inversion method. At the same time, a new framewo rk of 3-D shape modeling based on the combined analysisExpand


Adaptive optics observations of asteroid 216 Kleopatra
The large main-belt asteroid (216) Kleopatra has been for long suspected to be a binary object, mainly due to its large lightcurve amplitude. However, recent observations suggest that it is a singleExpand
New insights on the binary asteroid 121 Hermione
We report on the results of a six-month photometric study of the main-belt binary C-type asteroid 121 Hermione, performed during its 2007 opposition. We took advantage of the rare observationalExpand
Asteroid (216) Kleopatra - Tests of the radar-derived shape model
The shape model of Ostro et al. ([CITE]) for (216) Kleopatra – obtained from inversion of the radar data (Hudson & Ostro [CITE]) – is compared to the high resolution interferometric observations ofExpand
Figure of the double Asteroid 90 Antiope from adaptive optics and lightcurve observations
Abstract A long-term adaptive optics (AO) campaign of observing the double Asteroid (90) Antiope has been carried out in 2003–2005 using 8–10-m class telescopes, allowing prediction of theExpand
Photoelectric analysis of asteroid 216 Kleopatra: Implications for its shape
Abstract In some recent theoretical papers it has been suggested that gravitationally bound “rubble piles” in hydrostatic equilibrium possibly exist among the asteroids. For a higher-than-criticalExpand
Interpretation of the IAU Two-Parameter Magnitude System for Asteroids in Terms of Hapke Photometric Theory
Abstract In 1985 IAU Commission 20 adopted a two-parameter magnitude system for asteroids (Marsden, B. G. 1986, Minor Planet Circulars 10193 and 10194; Bowell, E., et al. 1989, in Asteroids II (R. P.Expand
First ground-based astrometric observations of Puck
Abstract The ten small inner moons of Uranus, discovered in 1986, have so far only been studied from space (Voyager 2, HST). The orbital elements derived from the observations indicate very weaklyExpand
Photometric and polarimetric observations and model simulations of (216) Kleopatra
We performed photometric and polarimetric observations, on November 8 and 9, 1999, of an M-type main belt asteroid, (216) Kleopatra by using the HBS spectropolarimeter installed at DodairaExpand
