Rossby Wave Instability

(RWI)
(type of disk instability that may be a factor in planet formation)

A Rossby Wave Instability (RWI) is a phenomenon in a Protoplanetary Disk or Accretion Disk whereby the disk changes from a smooth profile to less regular. Such an instability can occur in Rossby Waves of a Keplerian Disk under certain conditions.

Current theories of Planet Formation depend on this instability.
