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 …

Interferometric observations of magnetic fields in forming stars

CLH Hull, Q Zhang - Frontiers in Astronomy and Space Sciences, 2019 - frontiersin.org

One solution to the mass budget problem for planet formation: optically thick disks with dust scattering

Z Zhu, S Zhang, YF Jiang, A Kataoka… - The Astrophysical …, 2019 - iopscience.iop.org
Abstract Atacama Large Millimeter Array (ALMA) surveys have suggested that the dust in
Class II disks may not be enough to explain the averaged solid mass in exoplanets, under …

A multifrequency ALMA characterization of substructures in the GM Aur protoplanetary disk

J Huang, SM Andrews, CP Dullemond… - The Astrophysical …, 2020 - iopscience.iop.org
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 …

ALMA observations of polarized emission toward the CW Tau and DG Tau protoplanetary disks: constraints on dust grain growth and settling
