Abstract

We describe modeling of the ''beat'' and "bump" Cepheids, using the new radiative opacities. Discrepancies between these models and the evolutionary tracks for stars of appropriate mass are discussed. Finally, we point out some of the difficulties involving the long-period Cepheid sample with periods greater than 20 days.
