Planet-induced Vortices with Dust Coagulation in Protoplanetary Disks

14 Mar 2020 Li Ya-Ping Li Hui Li Shengtai Birnstiel Tilman Drazkowska Joanna Stammler Sebastian

In this work, we study how the dust coagulation/fragmentation will influence the evolution and observational appearances of vortices induced by a massive planet embedded in a low viscosity disk by performing global 2D high-resolution hydrodynamical simulations. Within the vortex, due to its higher gas surface density and steeper pressure gradients, dust coagulation, fragmentation and drift (to the vortex center) are all quite efficient, producing dust particles ranging from micron to $\sim 1.0\ {\rm cm}$, as well as overall high dust-to-gas ratio (above unity)...
