Abstract
The topological characterization of chaos is applied to the irregular pulsations of a model for a star of the W Virginis type, computed with a state-of-the-art numerical hydrodynamical code. The banded W Vir at tractor is found to possess an additional twist when compared to the R ossler band. It is shown that the stellar light-curve contains the sam e dynamical information about the attractor as the stellar radius or a s the radial velocity variations.
