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…

One-armed spirals in locally isothermal, radially structured self-gravitating discs

Min-Kai Lin

We describe a new mechanism that leads to the destabilisation of non-axisymmetric waves in astrophysical discs with an imposed radial temperature gradient. This might apply, for ex…

Polar alignment of a dusty circumbinary disc -- II. Application to 99 Herculis

Jeremy L. Smallwood, Min-Kai Lin, Rebecca Nealon +2

We investigate the formation of dust traffic jams in polar-aligning circumbinary discs. In our first paper, we found as the circumbinary disc evolves towards a polar configuration…

Stratified and vertically-shearing streaming instabilities in protoplanetary disks

Min-Kai Lin

Under the right conditions, the streaming instability between imperfectly coupled dust and gas is a powerful mechanism for planetesimal formation as it can concentrate dust grains…

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…

Puffed up Edges of Planet-opened Gaps in Protoplanetary Disks. I. hydrodynamic simulations

Jiaqing Bi, Min-Kai Lin, Ruobing Dong

Dust gaps and rings appear ubiquitous in bright protoplanetary disks. Disk-planet interaction with dust-trapping at the edges of planet-induced gaps is one plausible explanation. H…
