A New Method for Direct Measurement of Isotopologue Ratios in Protoplanetary Disks: A Case Study of the 12CO/13CO Ratio in the TW Hya Disk [PDF]
Astrophysical Journal, 2022 Planetary systems are thought to be born in protoplanetary disks. Isotope ratios are a powerful tool for investigating the material origin and evolution from molecular clouds to planetary systems via protoplanetary disks.

A Multifrequency ALMA Characterization of Substructures in the GM Aur Protoplanetary Disk [PDF]
Astrophysical Journal, 2020 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 outsized influence on our understanding of disk structure and evolution ...

Finding Substructures in Protostellar Disks in Ophiuchus
The Astronomical Journal, 2023 High-resolution, millimeter observations of disks at the protoplanetary stage reveal substructures such as gaps, rings, arcs, spirals, and cavities. While many protoplanetary disks host such substructures, only a few at the younger protostellar stage ...

Observations of Protoplanetary Disk Structures [PDF]
, 2020 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 conditions, reflect the underlying mechanisms that drive those ...

Rapid Evolution of Volatile CO from the Protostellar Disk Stage to the Protoplanetary Disk Stage [PDF]
Astrophysical Journal, 2020 Recent observations show that the CO gas abundance, relative to H2, in many 1–10 Myr old protoplanetary disks may be heavily depleted by a factor of 10–100 compared to the canonical interstellar medium (ISM) value of 10−4.

Protoplanetary Disk Rings as Sites for Planetesimal Formation [PDF]
, 2020 Axisymmetric dust rings are a ubiquitous feature of young protoplanetary disks. These rings are likely caused by pressure bumps in the gas profile; a small bump can induce a traffic-jam-like pattern in the dust density, while a large bump may halt radial

Modeling protoplanetary disk SEDs with artificial neural networks: Revisiting the viscous disk model and updated disk masses [PDF]
Astronomy & Astrophysics, 2020 We model the spectral energy distributions (SEDs) of 23 protoplanetary disks in the Taurus-Auriga star-forming region using detailed disk models and a Bayesian approach.

PPDONet: Deep Operator Networks for Fast Prediction of Steady-state Solutions in Disk–Planet Systems
The Astrophysical Journal Letters, 2023 We develop a tool, which we name Protoplanetary Disk Operator Network (PPDONet), that can predict the solution of disk–planet interactions in protoplanetary disks in real time.
