Recent spatially-resolved observations of protoplanetary disks revealed a plethora of
substructures, including concentric rings and gaps, inner cavities, misalignments, spiral …

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 …

We present an asymptotically and unconditionally stable numerical method to account for
the momentum transfer between multiple species. Momentum is conserved to machine …

Outflows driven by large-scale magnetic fields likely play an important role in the evolution
and dispersal of protoplanetary disks and in setting the conditions for planet formation. We …

The streaming instability is thought to play a central role in the early stages of planet
formation by enabling the efficient bypass of a number of barriers hindering the formation of …

Rings and gaps have been observed in a wide range of proto-planetary discs, from young
systems like HLTau to older discs like TW Hydra. Recent disc simulations have shown that …

The migration of planetary cores embedded in a protoplanetary disk is an important
mechanism within planet-formation theory, relevant for the architecture of planetary systems …

Recent studies have shown that the large-scale gas dynamics of protoplanetary disks
(PPDs) are controlled by nonideal magnetohydrodynamics (MHD), but how this influences …

Recent millimeter and infrared observations have shown that gap-and ring-like structures
are common in both dust thermal emission and scattered light of protoplanetary disks. We …

Previous axisymmetric investigations in two dimensions (2D) have shown that rings and
gaps develop naturally in non-ideal magnetohydrodynamic disc–wind systems, especially in …
