The strange polarimetric behavior of Asteroid (234) Barbara

Abstract We have discovered that the Asteroid (234) Barbara exhibits very anomalous polarimetric properties. The phase–polarization curve of this asteroid is unique and is not matched by any other known atmosphereless body of our Solar System. Although a few preliminary conjectures can be made, for the moment the reasons of the peculiar polarimetric properties of this asteroid remain essentially unknown.
