Circumstellar disks of planetary debris are now known or suspected to closely orbit
hundreds of white dwarf stars. To date, both data and theory support disks that are entirely …

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 …

Context. Large surveys with new-generation high-contrast imaging instruments are needed
to derive the frequency and properties of exoplanet populations with separations from~ 5 to …

The connection between the nature of a protoplanetary disk and that of a debris disk is not
well understood. Dust evolution, planet formation, and disk dissipation likely play a role in …

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 …

We report the discovery of a planetary-mass companion, HD 106906 b, with the new
Magellan Adaptive Optics (MagAO)+ Clio2 system. The companion is detected with Clio2 in …

We know little about the outermost exoplanets in planetary systems because our detection
methods are insensitive to moderate-mass planets on wide orbits. However, debris discs …

This paper presents a study of circumstellar debris around Sun-like stars using data from the
Herschel DEBRIS Key Programme. DEBRIS is an unbiased survey comprising the nearest∼ …

A substantial fraction of the lowest metallicity stars show very high enhancements in carbon.
It is debated whether these enhancements reflect the stars' birth composition, or if their …

Debris discs are evidence of the ongoing destructive collisions between planetesimals, and
their presence around stars also suggests that planets exist in these systems. In this paper …
