Sub-mm polarisation and asymmetry in the HD163296 protoplanetary rings
W.R.F.Dent, C.Pinte, P.Cortes, E.Fomalant et al

We present sub-mm wavelength images of dust emission and polarisation in the large protoplanetary disk around the 
Herbig Ae/Be star HD163296.
This disk has 3 bright rings in mm dust intensity. Polarisation fractions as high as 10% are seen, with interesting spatial 
features related to the rings.
We discuss these as well as asymmetries in the dust, and compare with recent SPHERE images in the near-ir.
