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.

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 ...

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 ...

Disk2Planet: A Robust and Automated Machine Learning Tool for Parameter Inference in Disk–Planet Systems [PDF]

The Astrophysical Journal
We 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 ...

Constraining the gas distribution in the PDS 70 disc as a method to assess the effect of planet-disc interactions [PDF]

Astronomy & Astrophysics, 2023
Context. Embedded planets are potentially the cause of substructures, such as gaps and cavities, observed in the continuum images of several protoplanetary discs. Likewise, gas distribution is expected to change in the presence of one or several planets, and the effect can be detected with current observational facilities.

Kinematic signatures of planet-disk interactions in VSI-turbulent protoplanetary disks [PDF]

Astronomy & Astrophysics, 2023
Context. Planets are thought to form inside weakly ionized regions of protoplanetary disks, where turbulence creates ideal conditions for solid growth. However, the nature of this turbulence is still uncertain. In this zone, vertical shear instability (VSI) can operate, inducing a low level of gas turbulence and large-scale motions. Resolving kinematic

Kinematic signatures of planet-disk interactions in vertical shear instability [PDF]

Astronomy & Astrophysics
Context. Planets are thought to form inside weakly ionized regions of protoplanetary disks, where turbulence creates ideal conditions for solid growth. However, the nature of this turbulence is still uncertain. In fast cooling parts of this zone the vertical shear instability (VSI) can operate, inducing a low level of gas turbulence and large-scale gas

Planet–Disk Interaction in Disks with Cooling: Basic Theory [PDF]

The Astrophysical Journal, 2020
Abstract Gravitational coupling between young planets and their parent disks is often explored using numerical simulations, which typically treat the disk thermodynamics in a highly simplified manner. In particular, many studies adopt the locally isothermal approximation, in which the disk temperature is a fixed function of the ...

Planet-Disk Interaction revisited [PDF]

EPJ Web of Conferences, 2013
We present results on our investigations of planet–disk interaction in protoplanetary disks. For the hydrodynamic simulations we use a second order semi–discrete total variation diminishing (TVD) scheme for systems of hyperbolic conservation laws on curvilinear grids.
