Observational Signature of Tightly Wound Spirals Driven by Buoyancy Resonances in Protoplanetary Disks

J Bae, R Teague, Z Zhu - The Astrophysical Journal, 2021 - iopscience.iop.org
Besides the spirals induced by the Lindblad resonances, planets can generate a family of
tightly wound spirals through buoyancy resonances. The excitation of buoyancy resonances …

Planet-disk-wind interaction: The magnetized fate of protoplanets

G Wafflard-Fernandez, G Lesur - Astronomy & Astrophysics, 2023 - aanda.org
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 α v …

Mean motion resonance capture in the context of type I migration

K Kajtazi, AC Petit, A Johansen - Astronomy & Astrophysics, 2023 - aanda.org
Capture into mean motion resonance (MMR) is an important dynamical mechanism because
it shapes the final architecture of a planetary system. We simulate systems of two or three …

Meridional circulation of dust and gas in the circumstellar disk: Delivery of solids onto the circumplanetary region

J Szulágyi, F Binkert, C Surville - The Astrophysical Journal, 2022 - iopscience.iop.org
We carried out 3D dust+ gas radiative hydrodynamic simulations of forming planets. We

Buoyancy response of a disc to an embedded planet: a cross-code comparison at high resolution

A Ziampras, SJ Paardekooper… - Monthly Notices of the …, 2023 - academic.oup.com
In radiatively inefficient, laminar protoplanetary discs, embedded planets can excite a
buoyancy response as gas gets deflected vertically near the planet. This results in vertical …

Migration of low-mass planets in inviscid discs: the effect of radiation transport on the dynamical corotation torque

A Ziampras, RP Nelson… - Monthly Notices of the …, 2024 - academic.oup.com
Low-mass planets migrate in the type-I regime. In the inviscid limit, the contrast between the
vortensity trapped inside the planet's corotating region and the background disc vortensity …

JJ Brown, GI Ogilvie - Monthly Notices of the Royal Astronomical …, 2024 - academic.oup.com
The key difficulty faced by 2D models for planet–disc interaction is in appropriately
accounting for the impact of the disc's vertical structure on the dynamics. 3D effects are often …
