Observations of protoplanetary disk structures

SM Andrews - Annual Review of Astronomy and Astrophysics, 2020 - annualreviews.org
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 …

An ALMA survey of protoplanetary disks in the σ Orionis cluster

M Ansdell, JP Williams, CF Manara… - The Astronomical …, 2017 - iopscience.iop.org
The σ Orionis cluster is important for studying protoplanetary disk evolution, as its

A stellar mass dependence of structured disks: a possible link with exoplanet demographics

N van der Marel, GD Mulders - The Astronomical Journal, 2021 - iopscience.iop.org
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 …

On the diversity of asymmetries in gapped protoplanetary disks

N Van der Marel, T Birnstiel, A Garufi… - The Astronomical …, 2020 - iopscience.iop.org
Protoplanetary disks with large inner dust cavities are thought to host massive planetary or
substellar companions. These disks show asymmetries and rings in the millimeter …
