Polarimetry of Comet Bradfield (1987s)
Abstract
Linear polarization measurements are reported for Comet Bradfield (1987s) at five effective wavelengths (380-730 nm) for phase angles 38-65 deg. Comparing the results with those for Comet Halley, it is found that: (1) the polarization is slightly but significantly stronger in Comet Bradfield at the corresponding phase angles, and (2) the wavelength dependence is similar.
