Fluid Dynamical Mechanisms for Knots in Astrophysical Jets
Abstract
The authors argue that fluid-dynamical instabilities (pinching and kinking) grow to nonlinear amplitude in knotty astrophysical jets and produce large-scale shock systems of the strength and distribution necessary to yield the observed knots. The behavior of fluid instabilities in the nonlinear regime and their saturation through shock formation is demonstrated by 2-dimensional gas dynamical simulations.
