Polarimetry of supernova SN 1987A - a dust shell model.
Abstract
Time variation of wavelength dependence of linear polarization is suggestive of a dust shell around SN 1987A. The intrinsic polarization is due to at least two components: one is due to a dust shell and the other is perhaps a synchrotron component. The minimum radius of the dust shell is estimated to be 0.04 pc with an optical thickness at visual wavelength 0.6. The temperature of the dust shell is expected to be Td ≡ 200K.
