Multi-Periodic Oscillations in Cepheids and RR Lyrae-Type Stars
arXiv:1208.4246 · doi:10.1007/978-3-642-29630-7_21
Abstract
Classical Cepheids and RR Lyrae-type stars are usually considered to be textbook examples of purely radial, strictly periodic pulsators. Not all the variables, however, conform to this simple picture. In this review I discuss different forms of multi-periodicity observed in Cepheids and RR Lyrae stars, including Blazhko effect and various types of radial and nonradial multi-mode oscillations.
