Large-scale persistent vortices are known to form easily in 2D disks via the Rossby wave or the baroclinic instability. In 3D, however, their formation and stability is a complex issue and still a matter of debate. We study the formation of vortices by the Rossby wave instability in a stratified inviscid disk and describe their three dimensional structure, stability and long term evolution. Numerical simulations are performed using a fully compressible hydrodynamical code based on a second… Expand
Vortices in stratified protoplanetary disks : From baroclinic instability to vortex layers
Large scale vortices could play a key role in the evolution of protoplanetary disks, particularly in the dead-zone where no turbulence associated with magnetic field is expected. Their possibleExpand
Parametric Study of the Rossby Wave Instability in a Two-dimensional Barotropic Disk. II. Nonlinear Calculations
Vortices in protoplanetary disks have attracted attention since the discovery of lopsided structures. One of the possible mechanisms for producing vortices is the Rossby Wave Instability (RWI). InExpand
Quasi-steady vortices in protoplanetary disks - I. From dwarfs to giants
Aims. We determine the size, structure, and evolution of persistent vortices in 2D and inviscid Keplerian flows. Methods. A Gaussian model of the vortices is built and compared with numericalExpand
Zombie Vortex Instability I: A Purely Hydrodynamic Instability to Resurrect the Dead Zones of Protoplanetary Disks
There is considerable interest in hydrodynamic instabilities in dead zones of protoplanetary disks as a mechanism for driving angular momentum transport and as a source of particle-trapping vorticesExpand
Are protoplanetary disks born with vortices? -- Rossby wave instability driven by protostellar infall
We carry out two-fluid, two-dimensional global hydrodynamic simulations to test whether protostellar infall can trigger Rossby wave instability (RWI) in protoplanetry disks. Our results show thatExpand
The structure and stability of vortices in astrophysical discs
This thesis finds that vortex instabilities are not necessarily a barrier to their potential as sites for planetesimal formation. It is challenging to build planetesimals from dust within theExpand
On the vortex evolution in non-isothermal protoplanetary discs
It is believed that large-scale horseshoe-like brightness asymmetries found in dozens of transitional protoplanetary discs are caused by anticyclonic vortices. These vortices can play a key role inExpand
Parametric Study of the Rossby Wave Instability in a Two-Dimensional Barotropic Disk
Protoplanetary disks with non-axisymmetric structures have been observed. The Rossby wave instability (RWI) is considered as one of the origins of the non-axisymmetric structures. We perform linearExpand
Vortex cycles at the inner edges of dead zones in protoplanetary disks
In protoplanetary disks, the inner boundary between the turbulent and laminar regions is a promising site for planet formation because solids may become trapped at the interface itself or in vorticesExpand
Long Term Evolution of Planet-Induced Vortices in Protoplanetary Disks
Recent observations of large-scale asymmetric features in protoplanetary disks suggest that large-scale vortices exist in such disks. Massive planets are known to be able to produce deep gaps inExpand


Rossby wave instability in 3D discs
The Rossby wave instability (RWI) is a promising mechanism for producing large-scale vortices in protoplanetary discs. The instability operates around a density bump in the disc, and the resultingExpand
