UW Astronomer: Karen Bjorkman

This star was observed on Mar 5, 1995 by WUPPE and on Mar 11, 1995 by HPOL at PBO.
The observations indicate that the polarization is due to scattering by electrons in a disk seen nearly edge on. The polarization cannot be due to dust unless all the dust grains in the disk are larger than the wavelength of light.
