PROTOPLANETARY DISK EVOLUTION

, 2004
One of the most active fields of research in accretion disk theory is understanding the mechanisms that transport angular momentum outward. Two instabilities are thought to be responsible for it in massive, magnetized disks: the magnetorotational instability (MRI) caused by the presence of a weak magnetic field, and gravitational instabilities.This PhD

SCExAO/CHARIS Near-infrared Scattered-light Imaging and Integral Field Spectropolarimetry of the AB Aurigae Protoplanetary System

The Astrophysical Journal
We analyze near-infrared integral field spectropolarimetry of the AB Aurigae protoplanetary disk and protoplanet (AB Aur b), obtained with SCExAO/CHARIS in 22 wavelength channels covering the J , H , and K passbands ( λ _0 = 1.1–2.4 μ m) over angular ...

Light Echoes of Protoplanetary Disks

The Astrophysical Journal
Light echoes offer a means of studying protoplanetary disks, including their geometry and composition, even when they are not spatially resolved. We present a test of this approach applied specifically to optically thick, geometrically flared disks ...
