Nonlinear Evolution of the Unstratified Polydisperse Dust Settling Instability
Hossam Aly, Sijme-Jan Paardekooper
Context. The Dust Settling Instabilty (DSI) is a member of the Resonant Drag Instabilities (RDI) family, and is thus related to the Streaming Instability (SI). Linear calculations…
Resonant drag instabilities for polydisperse dust. II. The streaming and settling instabilities
Sijme-Jan Paardekooper, Hossam Aly
Dust grains embedded in gas flow give rise to a class of hydrodynamic instabilities, called resonant drag instabilities. These instabilities have predominantly been studied for sin…
Resonant Drag Instabilities for Polydisperse Dust, I. The Acoustic Resonant Drag Instability
Sijme-Jan Paardekooper, Hossam Aly
Dust grains embedded in gas flow give rise to a class of hydrodynamic instabilities that can occur whenever there exists a relative velocity between gas and dust. These instabiliti…
Polydisperse Formation of Planetesimals: The dust size distribution in clumps
Jip Matthijsse, Hossam Aly, Sijme-Jan Paardekooper
The streaming instability is an efficient method for overcoming the barriers to planet formation in protoplanetary discs. The streaming instability has been extensively modelled by…
