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…
Local Simulations of Instabilities in Relativistic Jets I: Morphology and Energetics of the Current-Driven Instability
Sean M. O'Neill, Kris Beckwith, Mitchell C. Begelman
We present the results of a numerical investigation of current-driven instability in magnetized jets. Utilizing the well-tested, relativistic magnetohydrodynamic code Athena, we co…
