Turbulence In the Outer Regions of Protoplanetary Disks. II. Strong Accretion Driven by a Vertical Magnetic Field
Jacob B. Simon, Xue-Ning Bai, Philip J. Armitage +2
We carry out a series of local, vertically stratified shearing box simulations of protoplanetary disks that include ambipolar diffusion and a net vertical magnetic field. The ambip…
Turbulence In the Outer Regions of Protoplanetary Disks. I. Weak Accretion with No Vertical Magnetic Flux
Jacob B. Simon, Xue-Ning Bai, James M. Stone +2
We use local numerical simulations to investigate the strength and nature of magnetohydrodynamic (MHD) turbulence in the outer regions of protoplanetary disks, where ambipolar diff…
Emergent Mesoscale Phenomena in Magnetized Accretion Disc Turbulence
Jacob B. Simon, Kris Beckwith, Philip J. Armitage
We study how the structure and variability of magnetohydrodynamic (MHD) turbulence in accretion discs converge with domain size. Our results are based on a series of vertically str…
Turbulent Linewidths in Protoplanetary Disks: Predictions from Numerical Simulations
Jacob B. Simon, Philip J. Armitage, Kris Beckwith
Sub-mm observations of protoplanetary disks now approach the acuity needed to measure the turbulent broadening of molecular lines. These measurements constrain disk angular momentu…
