The Signature of Primordial Grain Growth in the Polarized Light of the AU Microscopii Debris Disk
The Signature of Primordial Grain Growth in the Polarized Light of the AU Microscopii Debris Disk
We have used the Hubble Space Telescope/ACS coronagraph to make polarization maps of the AU Mic debris disk. The fractional linear polarization rises monotonically from about 0.05 to 0.4 between 20 and 80 AU. The polarization is perpendicular to the disk, indicating that the scattered light originates from micron sized …
