The maximum-entropy method of spectrum analysis has been used to determine component periods in several variable stars of the dwarf Cepheid and Delta Scuti types. The method was tested on synthetic light curves, on the light curve of the well-studied dwarf Cepheid SX Phe, and on light curves of the Delta Scuti star Theta Tucanae, for which an extensive periodogram analysis exists. It was then applied to light curves of the stars HD 199757, Epsilon Cephei, 44 Tauri, 21 Comae, and HR 812. New secondary periods were found which have implications as to the nature of the variability. Finally, the potential of maximum-entropy spectrum analysis for future studies of variable stars is discussed briefly.
