Rossby Wave Instability in Astrophysical Discs

Abstract

A brief review is given of the Rossby wave instability (RWI) in astrophysical discs. In non-self-gravitating discs, around for example a newly forming stars, the instability can be triggered by an axisymmetric bump at some radius $r_0$ in the disc surface mass-density. It gives rise to exponentially growing non-axisymmetric perturbation [$\propto \exp (\mathrm{i}m\varphi )$, $m=1,\mathrm{2..}$] in the vicinity of $r_0$ consisting of {\it anticyclonic} vortices. These vortices are regions of high pressure and consequently act to trap dust particles which in turn can facilitate planetesimal growth in proto-planetary discs. The Rossby vortices in the discs around stars and black holes may cause the observed quasi-periodic modulations of the disc's thermal emission.
