Abstract

Mathematical research has yielded new time series methods, such as multi-taper spectral analysis, and wavelets and their extensions. The corresponding algorithms are rapidly being developed for unevenly sampled time series data, characteristic of astronomy and other sciences. Combinations of several new and old techniques yield powerful tools for detecting and characterizing periodic, quasiperiodic, and aperiodic signals. I describe several such combined methods and apply them to bizarrely spaced radial velocity data from one of the newly-discovered extrasolar planetary systems.
