Abstract Irregular components in the X-ray variability of Her X-1 have been investigated using new methods of data analysis. These methods are derived from the theory of dynamical systems. They enable a reconstruction of the attractor representing the process which is responsible for the temporal evolution of the observed X-ray luminosity. As a characteristic invariant of the attractor its dimension can be determined. For the X-ray radiation from the binary system Her X-1 / HZ Her as observed by the EXOSAT satellite, an attractor has been established which is of an intriguingly low dimension. This fact provides evidence for a non-stochastic, deterministic chaotic origin of the irregular variability of the emitted X-ray radiation. Higher dimensional chaos has also been found to govern the dynamical processes in the accretion disk of the system. Corresponding attractors have been derived for those phases when the X-ray source is partially obscured by the accretion disk.
