Rotational breakup as the origin of small binary asteroids

Nature, 2008
Asteroids with satellites are observed throughout the Solar System, from subkilometre near-Earth asteroid pairs to systems of large and distant bodies in the Kuiper belt. The smallest and closest systems are found among the near-Earth and small inner main-belt asteroids, which typically have rapidly rotating primaries and close secondaries on circular ...

Imaging unresolved rotating asteroids

Proceedings of SPIE, 1995
Abstract Most asteroids subtend extremely small angles in the sky so it is impossible to directly discerneither surface reflectivity, shape variations, or the spin axis using existing ground-based telescopesystems. A super-resolution inversion technique relates the lightcurves of a rotating asteroid, whichis represented as a polyhedron with planar ...

Physical study of asteroids: Ligthcurves and rotational periods of six asteroids

Icarus, 1984
Abstract V band photoelectric lightcurves and rotational periods are presented for six asteroids: 150 Nuwa, 203 Pompeja, 336 Lacaderia, 545 Messalina, 984 Gretia, and 1240 Fantasia. Except for 984 Gretia, none of these asteroids has been previously observed.

New rotational periods of 18 asteroids

Planetary and Space Science, 2000
Abstract The results of photoelectric observations of 18 main-belt asteroids are discussed. The V-band lightcurves, the B–V colors, and the values of the synodic rotational period are presented. There exists no previous determination of the period for 13 of them.

The origin and rotation of binary asteroids

2015
Binary asteroids were detected in a variety of dynamical populations, including Near-Earth Asteroids (NEAs), the main belt (MB), Trojans, and transneptunian objects (TNO). We discuss a new ???multi-impact??? model for origin of all classes of binary objects, including binary asteroids, Pluto???Charon, and the Earth???Moon systems. Basic elements of the

Slowly Rotating Asteroid 1999 GU3

Icarus, 2000
Abstract Optical and radar observations reveal that 1999 GU3 is sub-kilometer-sized object with a synodic period of 9.0 days, low visual and radar albedos, and colors more consistent with the ordinary chondrites than the vast majority of main-belt asteroids.

Primary Rotations of Paired Asteroids

2009
A population of small main-belt asteroids residing on closely similar orbits was revealed by Vokrouhlicky and Nesvorny (2008, Astron. J. 136, 280-290). We have estimated statistical significances of individual pairs (Pravec and Vokrouhlicky 2009, Icarus, in press) and started a photometry observing program to characterize their spin properties ...

Color Variations of Asteroids during Rotation

1982
A list of asteroids is presented, observed frequently for color variations during rotation as an evidence for spots on the surface.+(−)sign means redder (bluer) at maximum brightness, < means no detection larger than scatter; lightcurve amplitudes are added, polarisation measurements and/ or other color indices are taken from reference 5.
