Planet-Disk Interactions and the Convective Overstability. I. Low Mass Planets
M. Lehmann, M. K. Lin
Rapid inward migration driven by Type I torques threatens the survival of low-mass planets in their nascent protoplanetary disks (PPDs). Positive co-rotation torques offer a potent…

Convective Overstability in Radially Global Protoplanetary Disks. II. Impact on planetesimal formation
Marius Lehmann, Min-Kai Lin
The Convective Overstability (COS) is a hydrodynamic instability occurring in protoplanetary disk (PPD) regions with an adverse radial entropy gradient. It is a potential driver of…

Dust dynamics in radially convective regions of protoplanetary disks
Min-Kai Lin, Marius Lehmann
Hydrodynamic instabilities likely operate in protoplanetary disks. One candidate, Convective Overstability (COS), can be triggered in regions with a negative radial entropy gradien…
