A revised shape model of asteroid (216) Kleopatra
3D plausible orbital stability close to asteroid (216) Kleopatra
Recent data processing showed the existence of a difference that can reach 25 per cent for the dimensions of asteroid (216) Kleopatra between the radar observations and the light curves. We rebuild
The small binary asteroid ( 939 )
In understanding the composition and internal structure of asteroids, their density is perhaps the most diagnostic qua ntity. We aim here to characterize the surface composition, mutual orbit , size,


New insights on the binary asteroid 121 Hermione
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 of
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.
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 Dodaira
Radar Observations of Asteroids 7 Iris, 9 Metis, 12 Victoria, 216 Kleopatra, and 654 Zelinda
Abstract We report 13-cm wavelength radar observations of the mainbelt asteroids 7 Iris, 9 Metis, 12 Victoria, 216 Kleopatra, and 654 Zelinda obtained at Arecibo between 1980 and 1989. The echoes are
3-μm Spectrophotometric Survey of M- and E-Class Asteroids
Many asteroids show absorption features diagnostic of hydrated minerals in the 3-μm region of the spectrum. Reflectance studies in this region can determine the hydration state of surface minerals
Discovery of the triple asteroidal system 87 Sylvia
The unambiguous detection of a triple asteroidal system in the main belt, composed of a 280-km primary (87 Sylvia) and two small moonlets orbiting at 710 and 1,360 km, which was most probably formed through the disruptive collision of a parent asteroid.
