Scientific paper

The Bahcall-Schmidt-Soneira Galaxy potential can be fitted accurately by a Stäckel potential. This provides an effective third integral that can be used in the interpretation of the kinematics of various galactic populations. As an example the authors use Stäckel dynamics to analyze the observed kinematics of K giants in the Galactic halo. It is assumed that the stars are distributed on thin tube orbits (shell orbits). This is the Stäckel generalization of the circular orbit model in a spherical potential. The authors find that the observed line-of-sight velocity dispersion is reproduced for Galactic altitudes larger than 10 kpc.
