The structure and evolution of protoplanetary discs (PPDs) are largely governed by disc angular momentum transport, mediated by magnetic fields. In the most observable outer disc, ambipolar diffusion is the primary non-ideal magnetohydrodynamic (MHD) effect. In this work, we study the gas dynamics in outer PPDs by conducting a series of global three-dimensional non-ideal MHD simulations with ambipolar diffusion and net poloidal magnetic flux, using the Athena++ MHD code, with resolution… Expand


Dust settling and rings in the outer regions of protoplanetary discs subject to ambipolar diffusion
MHD turbulence plays a crucial role in the dust dynamics of protoplanetary discs. It affects planet formation, vertical settling and is one possible origin of the large scale axisymmetric structures,Expand
Global Simulations of the Vertical Shear Instability with Nonideal Magnetohydrodynamic Effects
The mechanisms of angular momentum transport and level of turbulence in protoplanetary disks (PPDs) are crucial for understanding many aspects of planet formation. In the recent years, it has beenExpand
Efficiency of Particle Trapping in the Outer Regions of Protoplanetary Disks
We investigate the strength of axisymmetric local pressure maxima (zonal flows) in the outer regions of protoplanetary disks, where ambipolar diffusion reduces turbulent stresses driven by theExpand
Thanatology in protoplanetary discs - The combined influence of Ohmic, Hall, and ambipolar diffusion on dead zones
Protoplanetary discs are poorly ionised due to their low temperatures and high column densities and are therefore subject to three “non-ideal” magnetohydrodynamic (MHD) effects: OhmicExpand
Evolution of Protoplanetary Discs with Magnetically Driven Disc Winds
Aims: We investigate the evolution of protoplanetary discs (PPDs hereafter) with magnetically driven disc winds and viscous heating. Methods: We consider an initially massive disc with ~0.1 Msun toExpand
Magnetorotational instability in magnetic diffusion dominated accretion discs
We investigate the stability of a partially ionized, differentially rotating, diffusive disc threaded by both azimuthal and vertical magnetic field. The general stability criterion of such a disc inExpand
Ring formation and dust dynamics in wind-driven protoplanetary discs: global simulations
Large-scale vertical magnetic fields are believed to play a key role in the evolution of protoplanetary discs. Associated with non-ideal effects, such as ambipolar diffusion, they are known to launchExpand
Origin of Weak Turbulence in the Outer Regions of Protoplanetary Disks
The mechanism behind angular momentum transport in protoplanetary disks, and whether this transport is turbulent in nature, is a fundamental issue in planet formation studies. Recent ALMAExpand
We present full 2π global three-dimensional stratified magnetohydrodynamic (MHD) simulations of accretion disks. We interpret our results in the context of protoplanetary disks. We investigate theExpand
Global simulations of protoplanetary disks with ohmic resistivity and ambipolar diffusion
Protoplanetary disks are believed to accrete onto their central T Tauri star because of magnetic stresses. Recently published shearing box simulations indicate that Ohmic resistivity, ambipolarExpand
