Global simulations of protoplanetary disks with net magnetic flux: I. Non-ideal MHD case
TL;DR: In this article, the authors present the first global simulations of a weakly ionized disk that exhibits large-scale magnetized winds and observe self-organization, resulting in axisymmetric rings of density and associated pressurebumps.

Global simulations of protoplanetary disks with net magnetic flux - I. Non-ideal MHD case
TL;DR: In this article, the authors present the first global simulations of a weakly ionized disk that exhibits large-scale magnetized winds and observe self-organization, resulting in axisymmetric rings of density and associated pressurebumps.
Self-organisation in protoplanetary discs. Global, non-stratified Hall-MHD simulations

TL;DR: In this paper, the authors investigate the behavior of global MRI-unstable disc models dominated by the Hall effect and characterise their dynamics, and conclude that Hall-MRI driven self-organisation is a plausible scenario that could explain some of the structures found in recent observations.

TL;DR: In this article, a 3D model of the giant planet migration in low-viscosity disks with 3D grid-based codes is presented. But the authors do not consider the impact of self-gravity on vortex formation and vortex-disc dynamics.
