Abstract

We present an analytical model for the cross section of a turbulent, radiative jet or wake. This model is appropriate for modeling HH jets, or "wakes" left behind by "astrophysical bullets". Even though the model is very simple, it has the benign property of only having four free parameters (the outer radius of the beam, the axial velocity, the velocity at the edge of the beam, and the turbulent velocity width), which can be derived by fitting the radial velocity and line width cross sections of an observed outflow. We illustrate how to do such fits using previously published spectroscopic data of the HH 110 jet.
