We present new high resolution imaging of a light-scattering dust ring and halo around the young star HD 35841. Using spectroscopic and polarimetric data from the Gemini Planet Imager in H-band (1.6 µm), we detect the highly inclined (i = 85 •) ring of debris down to a projected separation of ∼12 au (∼0. 12) for the first time. Optical imaging...

We have obtained Hubble Space Telescope (HST) STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling Kuiper Belt in radial extent (FWHM: ∼25 au, centered at ∼46 au), and a halo extending to ∼640 au. We find that the halo is significantly bluer than the ring,...
