Secular Instability and Planetesimal Formation in the Dust Layer

Abstract

Late in the gaseous phase of a protostellar disk, centimeter-sized bodies probably settle into a thin “dust layer” at the midplane. A velocity difference between the dust layer and the gas gives rise to turbulence, which prevents further settling and direct gravitational instability of the layer. The associated drag on the surface of the layer causes… (More)
