Planet-Disk Interaction and Orbital Evolution [PDF]
Annual Review of Astronomy and Astrophysics, 2012 As planets form and grow within gaseous protoplanetary disks, the mutual gravitational interaction between the disk and planet leads to the exchange of angular momentum and migration of the planet. We review current understanding of disk-planet interactions, focusing in particular on physical processes that determine the speed and direction of ...

Planet-disk-wind interaction: The magnetized fate of protoplanets
Astronomy and Astrophysics, 2023 Context. Models of a planet-disk interaction are mainly based on 2D and 3D viscous hydrodynamic simulations. In such models, accretion is classically prescribed by an αv parameter which characterizes the turbulent radial transport of angular momentum in the disk.

Modeling the nonaxisymmetric structure in the HD 163296 disk with planet-disk interaction [PDF]
Astronomy and Astrophysics, 2021 Context. High-resolution ALMA observations such as the DSHARP campaign have revealed a variety of rich substructures in numerous protoplanetary disks. These structures consist of rings, gaps, and asymmetric features. It has been debated whether planets can be accounted for among these substructures in the dust continuum.

Shoulder of Dust Rings Formed by Planet–Disk Interactions
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.

Observing planet-disk interaction in debris disks [PDF]
Astronomy and Astrophysics, 2012 Context. Structures in debris disks induced by planetdisk interaction are promising to provide valuable constraints on the existence and properties of embedded planets. Aims. We investigate the observability of structures in debris disks induced by planet-disk interaction. Methods.

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.

Astrophysical Journal Letters, 2018 Abstract The Disk Substructures at High Angular Resolution Project (DSHARP) provides a large sample of protoplanetary disks with substructures that could be induced by young forming planets. To explore the properties of planets that may be responsible for these substructures, we systematically carry out a grid of 2D hydrodynamical ...

Mind the Kinematics Simulation of Planet–Disk Interactions: Time Evolution and Numerical Resolution
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.

Astronomy and AstrophysicsContext. The multitude of different architectures found for evolved exoplanet systems are in all likelihood set during the initial planet-formation phase in the circumstellar disk. To understand this process, we have to study the earliest phases of planet formation. Aims.
