Combining asteroid models derived by lightcurve inversion with asteroidal occultation silhouettes

Abstrakt

We combine shape and spin state models of 44 asteroids (14 of them are new or updated models) with the available occultation data to derive asteroid effective diameters. In many cases, occultations allow us to reject one of two possible pole solutions that were derived from photometry.

We show that by combining results obtained from lightcurve inversion with occultation timings, we can obtain unique physical models of asteroids.
