Asteroid rotation rates

Icarus, 1979
Abstract A model for the evolution of the mean rotation rate of asteroids arising from mutual collisions yields reasonable agreement with observed rotation rates. The mean rotation rate of large asteroids for which gravitational binding energy exceeds material strength should be constant with respect to size.

Distribution and evolution of asteroid rotation rates

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1984
Data on the rotational characteristics of more than 300 asteroids are currently available and it is now clear that the distribution of the rotation rates is non-random. A plot of rotation rate against asteroid diameter shows large dispersion but is distinctly V-shaped. The minimum of this curve at ca.

Rotational properties of outer belt asteroids

Icarus, 1989
Abstract We present new photometric observations of 13 asteroids (153, 190, 225, 279, 334, 420, 483, 528, 588, 692, 721, 940, 1583) orbiting in the outer part of the belt, beyond the Hecuba gap at 3.3 AU from the Sun. The resulting periods and amplitudes are then used to compare the properties of a main-belt asteroid sample and an outer-belt sample ...

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.

Origin of asteroid rotation rates in catastrophic impacts

Nature, 1997
The rotation rates of asteroids, which are deduced from periodic fluctuations in their brightnesses, are controlled by mutual collisions. The link between asteroid spin and collision history is usually made with reference to impact experiments on centimetre-scale targets, where material strength governs the impact response.

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.

Rotational fission of contact binary asteroids

Icarus, 2007
The energetics and dynamics of contact binary asteroids as they approach and pass the rotational fission limit is studied. We presume that the asteroids are subject to an external torque, such as from the YORP effect, that increases their angular momentum.
