Streaming instabilities in weakly ionized protoplanetary discs: the Ambipolar Streaming Instability (AmSI)
Arnaud Pierens, Min-Kai Lin
The regions of protoplanetary discs where planets can form are believed to be weakly ionised, suggesting thereby that non-ideal magneto-hydrodynamics (MHD) effects play an importan…

Coexistence of coagulation and streaming instabilities in protoplanetary discs
Arnaud Pierens, Thomas Collin-Dufresne, Min-Kai Lin +1
The streaming instability is considered one of the leading candidates for the formation of planetesimals, due to its ability to overcome the bouncing and fragmentation barriers. Th…
