Abstract
We study the nonlinear evolution of Kelvin-Helmholtz instabilities in a cylindrical jet by numerical methods. In light jets, the instability saturates, leading to the formation of periodic shock structures, while, in heavy jets, it leads to a disruption of the jet. The separation between the shock waves is of the order of that observed in the case of knots in stellar jets. We discuss our results in the context of models for the interpretation of such knots.
