Shoulder of Dust Rings Formed by Planet–Disk Interactions [PDF]
The Astrophysical JournalRecent analyses of millimeter-wavelength protoplanetary disk observations have revealed several emission excesses on the previously identified dust rings, referred to as dust shoulders.

Mind the Kinematics Simulation of Planet–Disk Interactions: Time Evolution and Numerical Resolution [PDF]
The Astrophysical JournalPlanet–disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated.

PPDONet: Deep Operator Networks for Fast Prediction of Steady-state Solutions in Disk–Planet Systems [PDF]
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.

Planet-disk interactions in non-isothermal disks [PDF]
, 2015 Protoplanetary disks control the formation and evolution of planets, in reaction the planets also influence the disk structure. Disk gas and dust are the building materials of planets. Tidal forces between planet and disk determine the radial movement of the planet (migration); the planets simultaneously influence the disk, possibly carving out a gap ...

EAS Publications Series, 2008 Tides come from the fact that different parts of a system do not fall in exactly the same way in a non-uniform gravity field. In the case of a protoplanetary disk perturbed by an orbiting, prograde protoplanet, the protoplanet tides raise a wake in the disk which causes the orbital elements of the planet to change over time. The most spectacular result

Signatures of Planet-Disk Interaction and Disk Winds [PDF]
, 2022 Protoplanetary disks, consisting of gas and dust, are thought to be the birthplace of planets. Recent observations have revealed a multitude of substructures in the dust continuum and scattered light emission. It is unclear if these gaps, rings and asymmetries are signposts of embedded planets interacting with their surroundings, or if different ...

Disk2Planet: A Robust and Automated Machine Learning Tool for Parameter Inference in Disk–Planet Systems [PDF]
The Astrophysical JournalWe introduce Disk2Planet, a machine-learning-based tool to infer key parameters in disk–planet systems from observed protoplanetary disk structures. Disk2Planet takes as input the disk structures in the form of 2D density and velocity maps, and outputs ...

The Astrophysical Journal, 2023 Giant planets embedded in protoplanetary disks (PPDs) can create annulus density gaps around their orbits in the type-II regime, potentially responsible for the ubiquity of annular substructures observed in PPDs.

Planet−Disk Interactions and the Convective Overstability. I. Low-mass Planets
The Astrophysical JournalRapid inward migration driven by Type I torques threatens the survival of low-mass planets in their nascent protoplanetary disks (PPDs). Positive corotation torques offer a potential solution but require viscous diffusion to remain unsaturated.
