Opposition polarimetry and photometry of the low albedo asteroid 419 Aurelia
Abstract
Simultaneous photometric and polarimetric observations at small phase angles were carried out for the low albedo asteroid 419 Aurelia. Two interesting observational features were found: (1) a noticeable very narrow opposition surge in the asteroid magnitude phase curve at phase angles less than 0.6 deg; and (2) a decrease of both the depth and width of the negative polarization branch as compared to other dark asteroids with higher albedo. The significance of these results and their correspondence to available laboratory and theoretical studies are discussed.
