Dynamics of Dusty Vortices II: Stability of 2D dust laden vortices
Francesco Lovascio, Sijme-Jan Paardekooper, Colin McNally
Vortices have long been speculated to play a role in planet formation, via the collection of dust in the pressure maxima that arise at the cores of vortices in protoplanetary discs…
Vertical settling of pebbles in turbulent circumbinary discs and the in situ formation of circumbinary planets
Arnaud Pierens, Richard P. Nelson, Colin P. McNally
The inner-most regions of circumbinary discs are unstable to a parametric instability whose non-linear evolution is hydrodynamical turbulence. This results in significant particle…
Polydisperse Streaming Instability II. Methods for solving the linear stability problem
Sijme-Jan Paardekooper, Colin P. McNally, Francesco Lovascio
Occurring in protoplanetary discs composed of dust and gas, streaming instabilities are a favoured mechanism to drive the formation of planetesimals. The Polydispserse Streaming In…
Polydisperse Streaming Instability III. Dust evolution encourages fast instability
Colin P. McNally, Francesco Lovascio, Sijme-Jan Paardekooper
Planet formation via core accretion requires the production of km-sized planetesimals from cosmic dust. This process must overcome barriers to simple collisional growth, for which…
Polydisperse Streaming Instability I. Tightly coupled particles and the terminal velocity approximation
Sijme-Jan Paardekooper, Colin P. McNally, Francesco Lovascio
We introduce a polydisperse version of the streaming instability, where the dust component is treated as a continuum of sizes. We show that its behaviour is remarkably different fr…
Hydrodynamical turbulence in eccentric circumbinary discs and its impact on the in situ formation of circumbinary planets
Arnaud Pierens, Colin P. McNally, Richard P. Nelson
Eccentric gaseous discs are unstable to a parametric instability involving the resonant interaction between inertial-gravity waves and the eccentric mode in the disc. We present 3D…
