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 …

volatile elements in protoplanetary disks. To shed light on the key processes, we carry out a …

Mass estimates of a giant planet in a protoplanetary disk from the gap structures

KD Kanagawa, T Muto, H Tanaka… - The Astrophysical …, 2015 - iopscience.iop.org
ABSTRACT A giant planet embedded in a protoplanetary disk forms a gap. An analytic
relationship among the gap depth, planet mass M p, disk aspect ratio hp, and viscosity α has …

Mapping the Complex Kinematic Substructure in the TW Hya Disk
