Vortex-Induced Substructures in a Protoplanetary Disk

The co-existence of crescents and rings has been observed in protoplanetary disks in dust continuum emission, such as HD143006. The crescents in continuum emission have been proposed to be the dust-trapping vortices produced by the Rossby Wave Instability (RWI). We hypothesize that the RWI vortices could induce rings and gaps by driving density waves analogous to planets. We study the properties of density waves and substructures induced by vortices in 2D hydrodynamic simulations performed by Athena++ for a shearing box. In this work, we aim to find rings and gaps induced by vortices in disks comparable to ALMA dust continuum observations.
