We report the results of a∼ 4 yr direct imaging survey of 104 stars to resolve and
characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager …

We apply the vectorized non-negative matrix factorization (NMF) method to the post-
processing of the direct imaging data of exoplanetary systems such as circumstellar disks …

Spatially resolved scattered-light images of circumstellar debris in exoplanetary systems
constrain the physical properties and orbits of the dust particles in these systems. They also …

Context. HR 4796 A is surrounded by a debris disc, observed in scattered light as an
inclined ring with a high surface brightness. Past observations have raised several …

We present ALMA observations of the 0.88 millimeter dust continuum and the 13 CO and C
18 OJ= 3-2 line emission of the circumbinary disk HD 142527 at a spatial resolution of∼ 0 …

We present H-band observations of β Pic with the Gemini Planet Imager's (GPI's) polarimetry
mode that reveal the debris disk between∼ 0 farcs 3 (6 AU) and∼ 1 farcs 7 (33 AU), while …

The protoplanetary disks seen around Herbig Ae stars eventually dissipate leaving just a
tenuous debris disk, comprised of planetesimals and the dust derived from them, as well as …

Spatially resolved images of debris discs are necessary to determine disc morphological
properties and the scattering phase function (SPF) thatantifies the brightness of scattered …

ABSTRACT A" minimum model" for debris disks consists of a narrow ring of parent bodies,
secularly forced by a single planet on a possibly eccentric orbit, colliding to produce dust …

Context. The scattering properties of the dust originating from debris discs are still poorly
known. The analysis of scattered light is however a powerful remote-sensing tool to …
