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 …
