Abstract:
The observed irregular and very large amplitude variations that occur in 
some Cepheid variable stars remained a mystery for a long time. We show 
how the mechanism for this behavior can now be understood with modern 
nonlinear time-series analysis that consists of a phase-space 
reconstruction from the observed lightcurve data. Specifically 
demonstrate that the dynamics that underlies this behavior is a 
low-dimensional, and draw conlusions about the physical mechanism.
