Low-mass planet migration in three-dimensional wind-driven inviscid discs: a negative corotation torque
(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 ...
Multiplanet systems in inviscid discs can avoid forming resonant chains
(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 III. Dust evolution encourages fast instability
(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 ...
Polydisperse Streaming Instability II. Methods for solving the linear stability problem
(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 ...
