Efficiency of coherent vortices to trap dust particles in the solar nebula

Efficiency of coherent vortices to trap dust particles in the solar nebula

We develop the idea proposed by Barge & Sommeria (1995) that large-scale vortices present in the solar nebula can concentrate dust particles and facilitate the formation of planetesimals and planets. We introduce an exact vortex solution of the incompressible 2D Euler equation (Kida vortex) a...
