View article: Hydrodynamical simulations with strong indirect terms in FARGO-like codes
Hydrodynamical simulations with strong indirect terms in FARGO-like codes Open
Context . Binary star systems allow us to study the planet formation process under extreme conditions. In the early stages, these systems contain a circumbinary disk and a disk around each star. To model the interactions between these disk…

Survival of planet-induced vortices in 2D disks Open
Context. Several observations of protoplanetary disks reveal non-axisymmetric features, which are often interpreted as vortices. Numerical modeling has repeatedly shown that gap-opening planets are capable of producing large and long-lasti…

Migration of Jupiter-mass planets in low-viscosity discs Open
Context. Type-II migration of giant planets has a speed proportional to the disc’s viscosity for values of the α viscosity parameter larger than 10−4. Previous studies based on two-dimensional simulations, have shown that, at even lower vi…

Detecting vortices in fluid dynamics simulations using computer vision Open
Vortices are patches of fluid revolving around a central axis. They are ubiquitous in fluid dynamics. To the human eye, detecting vortices is a trivial task thanks to our inherent ability to identify patterns. To solve this task automatica…
