Accretion through circumstellar disks plays an important role in star formation and in
establishing the properties of the regions in which planets form and migrate. The …

We review recent advances in our understanding of magnetism in the solar nebula and
protoplanetary disks (PPDs). We discuss the implications of theory, meteorite …

" The study of planet formation has a long history. The idea that the Solar System formed
from a rotating disk of gas and dust-the Nebula Hypothesis-dates back to the writings of …

Context. The planet-forming region of protoplanetary disks is cold, dense, and therefore
weakly ionized. For this reason, magnetohydrodynamic (MHD) turbulence is thought to be …

The gas dynamics of weakly ionized protoplanetary disks (PPDs) are largely governed by
the coupling between gas and magnetic fields, described by three non-ideal …

Protoplanetary discs are poorly ionised due to their low temperatures and high column
densities and are therefore subject to three “non-ideal” magnetohydrodynamic (MHD) …

Protoplanetary disks (PPDs) are believed to accrete onto their central T Tauri star because
of magnetic stresses. Recently published shearing box simulations indicate that Ohmic …

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 …

This review examines recent theoretical developments in our understanding of turbulence in
cold, non-magnetically active, planetesimal-forming regions of protoplanetary disks that we …

We perform three-dimensional stratified shearing-box magnetohydrodynamic (MHD)
simulations on the gas dynamics of protoplanetary disks with a net vertical magnetic flux of B …
