Slowly-growing gap-opening planets trigger weaker vortices

Abstract The presence of a giant planet in a low-viscosity disc can create a gap edge in the disc's radial density profile sharp enough to excite the Rossby wave instability. This instability may evolve into dust-trapping vortices that might explain the ‘banana-shaped’ features in recently obse...
