dc.description.abstractObservations of protoplanetary disks have revealed both crescents and rings in dust continuum emission. These crescents are believed to result from dust-trapping vortices generated by the Rossby Wave Instability (RWI), which induces density waves similar to those produced by planets. We explore the properties of these density waves and associated substructures by performing 2D hydrodynamic simulations both in shearing boxes and global disks. Our findings confirm that long-lived vortices can indeed create observable rings and gaps in inviscid discs consistent with ALMA dust continuum observations. Additionally, we establish an empirical relationship between the aspect ratio of gas vortices and the location of dust rings, revealing a linear correlation between them.
