Since Protostars and Planets VI (PPVI), our knowledge of the global properties of
protoplanetary and debris disks, as well as of young stars, has dramatically improved. At the …

We provide a nonspecialist overview of the current state of understanding of the structure
and origin of our Solar System's transneptunian region (often called the Kuiper Belt) …

Gaps in protoplanetary disks have long been hailed as signposts of planet formation.
However, a direct link between exoplanets and disks remains hard to identify. We present a …

We present 1.3 mm continuum ALMA long-baseline observations at 3–5 au resolution of 10
of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project …

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 …

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 …

Since the discovery of the multiring structure of the HL Tau disk, ALMA data suggest that the
dust continuum emission of many, if not all, protoplanetary disks consists of rings and gaps …

Protoplanetary disks surrounding young stars are the birth place of planets. Of particular
interest are the transition disks with large inner dust cavities of tens of au, hinting at the …

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 …

Debris belts on the periphery of planetary systems, encompassing the region occupied by
planetary orbits, are massive analogues of the Solar system's Kuiper belt. They are detected …
