From spirals to rings: dust dynamics in gravitoturbulent protoplanetary discs after late infall
Clément Baruteau, Steven Rendon Restrepo, Gaylor Wafflard-Fernandez +7
Substructures appear to be a common trait of all extended protoplanetary discs. They are found notably in discs still surrounded by ambient, possibly infalling material. In this st…
Self-gravity in thin protoplanetary discs: 2. Numerical convergence solved and revealing the overestimation in mass of formed planets with softening
S. Rendon Restrepo
The Gravitational Instability (GI) is a leading theory for explaining early planet formation in massive discs. In the early 2010s, 3D SPH simulations of GI failed to converge, init…
Self-gravity in thin protoplanetary discs: 1. The smoothing-length approximation versus the exact self-gravity kernel
S. Rendon Restrepo, T. Rometsch, U. Ziegler +1
Planet-forming discs often contain structures like spiral arms, typically linked to the disc's gravitational forces. In 2D models, an ad hoc softening prescription is commonly used…
Gravito-turbulent bi-fluid protoplanetary discs: 1. An analytical perspective to stratification
S. Rendon Restrepo, U. Ziegler, M. Villenave +1
Context. In Class 0/I and the outskirts of Class II circumstellar discs, the self-gravity of gas significantly affects the disc's vertical hydrostatic equilibrium. The contribution…
FargoCPT: A 2D Multi-Physics Code for Simulating the Interaction of Disks with Stars, Planets and Particles
Thomas Rometsch, Lucas M. Jordan, Tobias W. Moldenhauer +6
Context: Planet-disk interactions play a crucial role in the understanding of planet formation and disk evolution. There are multiple numerical tools available to simulate these in…
Self-gravity in thin-disc simulations of protoplanetary discs: smoothing length rectified and generalised to bi-fluids
Steven Rendon Restrepo, Pierre Barge
To mimic protoplanetary discs (PPDs) evolution, 2D simulations with self-gravity must introduce a softening prescription of the gravitational potential. When the disc is only made…
Morphology and dynamical stability of self-gravitating vortices: Numerical simulations
Steven Rendon Restrepo, Pierre Barge
Theoretical and numerical studies have shown that large-scale vortices in Protoplanetary discs can result from various hydrodynamical instabilities. Once produced, such vortices ca…
RoSSBi3D: a 3D and bi-fluid code for protoplanetary discs
Steven Rendon Restrepo, Pierre Barge, Radim Vavrik
The diversity of the structures recently observed in protoplanetary discs (PPDs) with the new generation of high-resolution instruments have made more acute the challenging questio…
