Icarus, 1980
Photoelectric observations of 32 asteroids observed from Table Mountain Observatory during the second half of 1978 are reported. Rotation periods were obtained for most objects. Absolute magnitudes and phase functions were not determined for any of these asteroids.

On the shape of rapidly rotating asteroids
Advances in Space Research, 1981Abstract By means of a statistical analysis of the rotational properties of asteroids, we define a class of large amplitude and short period objects (LASPA). A possible interpretation of their collisional evolution and present physical status, in terms of ellipsoidal figures of equilibrium, is proposed.

Icarus, 1984
A trend of increasing mean rotational frequency with increasing diameter is noted in asteroids with diameters greater than 120 km, irrespective of M-, S-, and C-type asteroid subset and family or nonfamily membership. This trend cannot be accounted for by observational selection.

The axial rotation of asteroids
Astrophysics and Space Science, 1970The observed fact that light changes of the asteroids exhibit no beat periods is interpreted as an indication that they do not wobble in space like spinning tops, but spin about only one axis (possibly — but not necessarily — inclined but little to the plane of their orbits).

The rotation of asteroid (16) Psyche
Chinese Astronomy and Astrophysics, 1982Abstract We used observations at 4 oppositions to calculate the rotation of the asteroid (16) Psyche. Our results are 1) the pole is λ 225°, β = +5° (1950.0), 2) the rotation is direct, and 3) the sidereal period is 4h 11m 45s.42 ± 0s.01. At the three oppositions of 1955, 1965 and 1980, the relative positions of the Sun, the Earth and the asteroids ...

On the Rotations of M Asteroids
1982According to the theory of collisional evolution of asteroid rotations by Harris (1979) the densest objects should have the highest average spin rates. Since it is widely believed that M asteroids are of metallic composition, this theory predicts that they rotate more rapidly than the stony C or S objects. Harris and Burns (1979) found indications that

The rotation of small asteroids
Icarus, 1984The Binzel and Mulholland (1983) sample of photoelectrically determined rotational parameters for 17 main belt asteroids with diameters less than 30 km are compared with previous observations of asteroids of that size range. Rigorous statistical tests are applied to investigate bias effects and quantify results on asteroid rotation.

Fast and Slow Rotation of Asteroids
Icarus, 2000Abstract We present an analysis of the distribution of asteroid spin rates vs. size. The existence of significant populations of both slow and fast rotators among asteroids smaller than D=40 km, and especially below 10 km (where our sample is mostly near-Earth asteroids), is shown.

Rotational periods of asteroids II
Planetary and Space Science, 2001Abstract In the framework of the photoelectric asteroid observational program undertaken at Catania University to collect lightcurves apt to apply the pole computational methods, the V-band lightcurves and the values of the synodic rotational period and of the average B–V colour index of 5 Astrea, 6 Hebe, 12 Victoria, 13 Egeria, 26 Proserpina, 34 ...
