Abstract

A stable self-consistent stellar dynamical model for the Galactic bar is constructed from about 500 numerically computed orbits with an extension of the Schwarzschild technique. The model fits the COBE found asymmetric boxy light distribution and the observed stellar kinematics of the bulge. The model is also consistent with the non-circular motions of the HI and CO velocity maps of the inner Galaxy, and the microlensing event rate towards the bulge. The technique used here can also be applied to interpret light and velocity data of external systems.
