Abstract

The Gemini Planet Imager (GPI) is a near-infrared high-contrast imager on the 8-m Gemini South telescope, optimized for the direct detection and characterization of extrasolar Jovian-mass planets and circumstellar disks. The instrument includes a dual-channel polarimetry mode designed to detect the inherently polarized light scattered off debris disks and protoplanetary disks and suppress unpolarized light from the host star. GPI has imaged over two dozen circumstellar disks {detecting some for the first time in scattered light {and carried out polarimetric measurements of brown dwarfs and exoplanets. Here, we review the current status of the debris disk component of the GPI Exoplanet Survey and report on updates to standard data reduction techniques that improve upon the achievable polarimetric contrasts.
