The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

This review addresses the state of research that employs astronomical (remote sensing)
observations of solids (“dust”) in young circumstellar disks to learn about planet formation …

Abstract The Disk Substructures at High Angular Resolution Project (DSHARP) is the largest
homogeneous high-resolution (∼ 0 farcs 035, or∼ 5 au) disk continuum imaging survey …

Context. Recent years have seen building evidence that planet formation starts early, in the
first~ 0.5 Myr. Studying the dust masses available in young disks enables us to understand …

The latest observation of HL Tau by ALMA revealed spectacular concentric dust rings in its
circumstellar disk. We attempt to explain the multiple ring structure as a consequence of …

We present a new method to constrain the grain size in protoplanetary disks with
polarization observations at millimeter wavelengths. If dust grains are grown to the size …

Context. Exoplanet atmospheres are thought be built up from accretion of gas as well as
pebbles and planetesimals in the midplanes of planet-forming disks. The chemical …

The mechanisms causing millimeter-wave polarization in protoplanetary disks are under
debate. To disentangle the polarization mechanisms, we observe the protoplanetary disk …

The protoplanetary disk around the T Tauri star GM Aur was one of the first hypothesized to
be in the midst of being cleared out by a forming planet. As a result, GM Aur has had an …

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 …
