Pole Determinations of Asteroids
Abstract
Pole positions, senses of rotation, and triaxial model shapes of six asteroids are presented. We derive prograde sense of rotation for 32 Pomona. For 201 Penelope a previous inconsistency in the determined sense of rotation is resolved in favor of the retrograde one. We confirm and improve on previous results for 3 Juno, 5 Astraea, 10 Hygiea, and 250 Bettina. The analysis is based on epochs, amplitudes, and magnitudes of published photometric lightcurves.
