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 …

The solid content of circumstellar disks is inherited from the interstellar medium: dust
particles of at most a micrometer in size. Protoplanetary disks are the environment where …

Abstract We introduce the Disk Substructures at High Angular Resolution Project (DSHARP),
one of the initial Large Programs conducted with the Atacama Large Millimeter/submillimeter …

We present a high-resolution (∼ 0 farcs 12,∼ 16 au, mean sensitivity of 50 μJy beam− 1 at
225 GHz) snapshot survey of 32 protoplanetary disks around young stars with spectral type …

The recent ALMA observations of the disk surrounding HL Tau reveal a very complex dust
spatial distribution. We present a radiative transfer model accounting for the observed gaps …

We present long baseline Atacama Large Millimeter/submillimeter Array (ALMA)
observations of the 870 μm continuum emission from the nearest gas-rich protoplanetary …

Context. Transition disks are protoplanetary disks with dust-depleted cavities, possibly
indicating substantial clearing of their dust content by a massive companion. For several …

Gravitational forces are expected to excite spiral density waves in protoplanetary disks, disks
of gas and dust orbiting young stars. However, previous observations that showed spiral …

The formation of planetary cores must proceed rapidly in order for the giant planets to
accrete their gaseous envelopes before the dissipation of the protoplanetary gas disc (≲ 3 …

Turbulence is a fundamental parameter in models of grain growth during the early stages of
planet formation. As such, observational constraints on its magnitude are crucial. Here we …
