Information on the enclosed mass and stellar number density
distribution allows to derive realistic potentials to study
stellar orbits. We present the results of calculations
using a 4th-order Hermite integrator. They provide
valuable additional information on the three dimensional
distribution and dynamics of different stellar populations
(He-, CO-, and high velocity stars) in the central cluster.
Especially for the He-stars the results are discussed in the
context of published kinematical models of the mini-spiral.
Constrains on the three distribution of the He-stars have
consequences on the heating of the dust in the mini-spiral
and on the accreting process for the central X-ray variable
This analysis also allows us to derive estimates for the
expected Newtonian periastron rotation of stellar orbits.
