Puffed-up Edges of Planet-opened Gaps in Protoplanetary Disks. II. The Role of the Planet's Orbital Eccentricity
Jiaqing Bi, Min-Kai Lin
Eccentric planets constitute a large population of known exoplanets and may drive significant substructures in protoplanetary disks through planet-disk interactions if their eccent…
Diffusive Instabilities in Dusty Disks: Linear Growth and Nonlinear Breakdown
Konstantin Gerbig, Min-Kai Lin
We revisit the diffusive instability in dusty disks that arises when the dust mass diffusivity and/or viscosity decreases sufficiently steeply with increasing dust density. Our upd…
Filament formation due to diffusive instabilities in dusty protoplanetary disks
Konstantin Gerbig, Min-Kai Lin, Marius Lehmann
We report the finding of a new, local diffusion instability in a protoplanetary disk, which can operate in a dust fluid, subject to mass diffusion, shear viscosity, and dust-gas dr…
Shoulder of Dust Rings Formed by Planet-disk Interactions
Jiaqing Bi, Min-Kai Lin
Recent analyses of mm-wavelength protoplanetary disk observations have revealed several emission excesses on the previously identified dust rings, referred to as dust shoulders. Th…
