Abstract: The distribution of chaos in self-consistent models of barred galaxies is investigated using Kolmogorov-Sinai entropy. This quantity describes the rate of divergence of neighbouring trajectories. The models are constructed with Schwarzschild's (1979) method which combines orbits as elementary building blocks. We display and discuss the mass distribution inside a bar as a function of the nature of the orbits (regular, chaotic or semi-chaotic).
