Turbulence Regulates the Rate of Planetesimal Formation via Gravitational Collapse
Daniel A. Gole, Jacob B. Simon, Rixin Li +2
We study how the interaction between the streaming instability and intrinsic gas-phase turbulence affects planetesimal formation via gravitational collapse in protoplanetary disks.…

The Nature of Turbulence in the Outer Regions of Protoplanetary Disks
Daniel A. Gole, Jacob B. Simon
We carry out a series of local, shearing box simulations of the outer regions of protoplanetary disks, where ambipolar diffusion is important due to low ionization levels, to bette…

Turbulence, Transport and Waves in Ohmic Dead Zones
Daniel Gole, Jacob B. Simon, Stephen H. Lubow +1
We use local numerical simulations to study a vertically stratified accretion disk with a resistive mid-plane that damps magnetohydrodynamic (MHD) turbulence. This is an idealized…
