Buoyancy response of a disc to an embedded planet: a cross-code comparison at high resolution
Ziampras, A; Paardekooper, S-J; Nelson, RP (Oxford University Press (OUP), 2023-09-11)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 oscillations that drive a vortensity ... -
Constraining the masses of planets in protoplanetary discs from the presence or absence of vortices - comparison with ALMA observations
Hallam, PD; Paardekooper, S-J (Published by Oxford University Press on behalf of the Royal Astronomical Society, 2020-02)A massive planet in a protoplanetary disc will open a gap in the disc material. A steep gap edge can be hydrodynamically unstable, which results in the formation of vortices that can act as tracers for the presence of ... -
Dynamics of dusty vortices - I. Extensions and limitations of the terminal velocity approximation
Lovascio, F; Paardekooper, S-J (Published by Oxford University Press on behalf of the Royal Astronomical Society, 2019-10)Motivated by the stability of dust laden vortices, in this paper we study the terminal velocity approximation equations for a gas coupled to a pressureless dust fluid and present a numerical solver for the equations embedded ... -

Low-mass planet migration in three-dimensional wind-driven inviscid discs: a negative corotation torque
McNally, CP; Nelson, RP; Paardekooper, S-J; Benítez-Llambay, P; Gressel, O (Oxford University Press (OUP), 2020-02-28)We present simulations of low-mass planet–disc interactions in inviscid three-dimensional discs. We show that a wind-driven laminar accretion flow through the surface layers of the disc does not significantly modify the ... -
Migrating super-Earths in low-viscosity discs: unveiling the roles of feedback, vortices, and laminar accretion flows

Migration of low-mass planets in inviscid discs: the effect of radiation transport on the dynamical corotation torque
Ziampras, A; Nelson, RP; Paardekooper, S-J (Oxford University Press (OUP), 2024-02-15)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 leads to a dynamical corotation ... -

Multiplanet systems in inviscid discs can avoid forming resonant chains
McNally, CP; Nelson, RP; Paardekooper, S-J (Oxford University Press (OUP), 2019-07-25)<jats:title>ABSTRACT</jats:title> <jats:p>Convergent migration involving multiple planets embedded in a viscous protoplanetary disc is expected to produce a chain of planets in mean motion resonances (MMRs), but the ... -
Polydisperse Streaming Instability II. Methods for solving the linear stability problem
Paardekooper, S-J; McNally, CP; Lovascio, F (Oxford University Press, 2021-01-19)Occurring in protoplanetary discs composed of dust and gas, streaming instabilities are a favoured mechanism to drive the formation of planetesimals. The polydispserse streaming instability is a generalization of the ... -
Polydisperse Streaming Instability III. Dust evolution encourages fast instability
McNally, CP; Lovascio, F; Paardekooper, S-J (Oxford University Press, 2021-01-19)Planet formation via core accretion requires the production of kilometre-sized planetesimals from cosmic dust. This process must overcome barriers to simple collisional growth, for which the streaming instability (SI) is ... -
