Abstract The interaction of the accreting mass and the X-ray radiation of a spherically accreting neutron star is described by a discrete — time dynamical model. Its main feature consists of a nonlinear feedback mechanism between mass accretion and escaping radiation. The model is studied with respect to its stability properties and its astrophysical implications. As a function of time, we obtain stationary, periodic, and chaotic luminosities. The different kinds of behavior occur in different regimes of the mass accretion rate.
