Shadow-induced Warps in Protoplanetary Disks

The Astrophysical Journal Letters
Shadows are commonly observed in protoplanetary disks in near-infrared (NIR) and (sub)millimeter images, often cast by misaligned inner disks or other obscuring material.

SO Emission in the Dynamically Perturbed Protoplanetary Disks around CQ Tau and MWC 758

The Astrophysical Journal
We report the serendipitous detection of the SO J _N  = 6 _5 –5 _4 (219.949 GHz) rotational transition in archival Atacama Large Millimeter/submillimeter Array observations of the spiral hosting protoplanetary disks around CQ Tau (with ≈4.9 σ ...

Observability of Substructures in the Planet-forming Disk in the (Sub)centimeter Wavelength with SKA and ngVLA

The Astrophysical Journal
Current imaging observations of protoplanetary disks using the Atacama Large Millimeter/submillimeter Array (ALMA) primarily focus on the submillimeter wavelength, leaving a gap in effective observational approaches for centimeter-sized dust, which is ...

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

Molecular Gas Tracers in Young and Old Protoplanetary Disks

The Astrophysical Journal
Molecular emission is used to investigate both the physical and chemical properties of protoplanetary disks. Therefore, to derive disk properties accurately, we need a thorough understanding of the behavior of the molecular probes upon which we rely ...
