These are the proceedings of a symposium devoted to astronomical time series. With the rising quantity, quality, and variety of temporal data, increasingly higher levels of sophistication are required of astronomers analyzing time series. Many of the central questions in astrophysics hinge on their measurement and analysis. The purpose of the meeting was to discuss some of the many recent applications, discoveries, problems and techniques of astronomical time series, and to bring to light the similarity of time series problems arising in different sub-disciplines. Contributions by some of the foremost experts in astronomical time series include the fields of general mathematical and statistical techniques, interacting binaries, planet searches, pulsars, gravitational lensing, and active galactic nuclei. The volume is a unique interdisciplinary compilation on the topic of astronomical time series, and is suitable as a graduate-level introduction to the various topics, as well as a reference for time-series related work.
