Spins, Lightcurves, and Binarity of Eight Asteroid Pairs: 4905, 7745, 8306 16815, 17288, 26416, 42946, and 74096
Abstract
Asteroid pairs are two asteroids found to share almost identical orbital elements. Studies have shown that each pair had a single progenitor that split in the last couple of million years due to rotational-fission of a "rubble-pile" structured body. Here we report the lightcurves and spins of eight primary members of asteroid pairs observed at the Wise Observatory in Israel. The lightcurves of two of the observed asteroids present light attenuation in addition to the standard periodicity; these are most probably the results of satellites causing mutual events of eclipse and occultation.
