Turbulence Can Persist in the Inner Regions of Weakly-Ionized Planet Forming Disks
David G. Rea, Jacob B. Simon
Identifying the mechanisms responsible for angular momentum transport in protoplanetary disks, and the extent to which those mechanisms produce turbulence, is a crucial problem in…

The Streaming Instability in 3D: Conditions for Strong Clumping
Jeonghoon Lim, Jacob B. Simon, Rixin Li +3
The streaming instability (SI) is a leading mechanism for planetesimal formation, driving the aerodynamic concentration of solids in protoplanetary disks. The SI triggers strong cl…

Turbulence Inhibits Planetesimal Formation in Class 0/I Disks Subject to Infall
Daniel Carrera, Abigail Davenport, Jacob B. Simon +5
There is growing evidence that planet formation begins early, within the Myr Class 0/I phase, when infall dominates disk dynamics. Our goal is to determine if Class 0/I…
