Physical studies of asteroids XVI - Photoelectric photometry of 17 asteroids
Abstract
The authors present photoelectric photometry of 17 asteroids observed during the period 1979 - 1986. Composite lightcurves have been derived for 76, 236, 439, 516 and 591, and at least a reasonable single-lightcurve coverage has been obtained for the majority of the remaining ones. Reference is made to Tholen's (1984) taxonomic classification and a brief discussion of lightcurve statistics in this framework is given. Differences between the spin rates and amplitudes of the C, S and M classes are considered and previous conclusions regarding the peculiar characteristics of M asteroids are confirmed. An indication is found that C and S asteroids have a particularly slow spin when situated near the 3/1 or 5/2 Kirkwood gaps.
