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…
Thermal structure of circumbinary discs: Circumbinary planets should be icy not rocky
Arnaud Pierens, Richard P. Nelson
The process of forming a circumbinary planet is thought to be intimately related to the structure of the nascent circumbinary disc. It has been shown that the structure of a circum…
On the growth and evolution of low-mass planets in pressure bumps
Arnaud Pierens, Sean N. Raymond
Observations of protoplanetary discs have revealed dust rings which are likely due to the presence of pressure bumps in the disc. Because these structures tend to trap drifting peb…
Three-dimensional evolution of radiative circumbinary discs: the size and shape of the inner cavity
Arnaud Pierens, Richard Nelson
The evolution of circumbinary discs and planets is often studied using two-dimensional (2D) numerical simulations, although recent work suggests that 3D effects may significantly a…
On the evolution of pebble-accreting planets in evolving protoplanetary discs
Arnaud Pierens
We examine the migration of luminous low-mass cores in laminar protoplanetary discs where accretion occurs mainly because of disc winds and where the planet luminosity is generated…
