Imaging polarimetry of cometary dust: different comets and phase angles

Levasseur-Regourd, A. C.; Hadamcik, E.

Polarimetric observations of the light scattered by dust in cometary comae have been carried out at Pic-du-Midi Observatory and at Haute-Provence Observatory (France) between 1990 and 2001. The whole coma polarization can easily be inferred from integration of the fluxes on the aperture. Maps are obtained for seven comets by CCD imaging polarimetr…
