Numerical simulation of the gravitational instability in the dust layer of a protoplanetary disk using a thin disk model - Dependence of results on given perturbations -

Abstract

We performed numerical simulations of the gravitational instability of the dust layer in a protoplanetary disk. We compared results begin with Q=5 and 2. We also compared results for perturbations given once initially, and continually at each Keplerian shear.
