Scientific paper

The radial pulsations of state-of-the-art population II Cepheid models are studied with a numerical hydrodynamical code. It is shown (a) that they can undergo a targent bifurcation which manifests itself as an abrupt change from periodical to irregular variability as a control parameter, Teff, is varied and (b) that the chaotic attractor seems to be embedded in a three-dimensional subspace of the 180-dimensional phase-space of the computations.
