Several observations of protoplanetary disks display non-axisymmetric features, often interpreted as vortices. Numerical modeling has repeatedly shown that gap-opening planets are capable of producing large and long-lasting vortices at their outer gap edge, making massive planets popular candidates as the source of such features.
In this talk, I present our recent numerical study on the lifetime of such planet-induced vortices in which we investigated how the lifetime of vortices depends on the viscosity, self-gravity, and radiative effects. The talk includes a brief introduction to vortices in protoplanetary disks and the numerical methods used to simulate them, a discussion of our findings, and the process we used to identify vortices in our simulation data.
