Gaps, rings, and non-axisymmetric structures in protoplanetary disks: Emission from large grains
Jan Philipp Ruge,Mario Flock,Mario Flock,Sebastian Wolf,Natalia Dzyurkevich,S. Fromang,Th. Henning,Hubert Klahr,H. Méheut,H. Méheut +9 more
TL;DR: In this article, the influence of the spatial distribution of these grains on the (sub)mm appearance of magnetized protoplanetary disks was investigated, and the feasibility of observing specific structures in the thermal re-emission maps with the Atacama Large Millimeter/submillimeter Array (ALMA) was investigated.

Toward a new paradigm for Type II migration
TL;DR: In this article, the authors show that the role of gap-crossing flows is in fact negligible and that the migration rate of a gap-opening planet is proportional to the disk's viscosity, but not equal to the gas drift speed in the unperturbed disk.
Toward a new paradigm for Type II migration
TL;DR: In this paper, the authors show that the role of gap-crossing flows is in fact negligible and propose a new paradigm for type II migration: a giant planet feels a torque from the disk that promotes its migration, while the gap profile relative to the planet is restored.
Migration of Jupiter-mass planets in low-viscosity discs
Elena Lega,Richard P. Nelson,Alessandro Morbidelli,Willy Kley,William Béthune,A. Crida,D. Kloster,H. Méheut,Thomas Rometsch,Alexandros Ziampras +9 more
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.
