Definition

A time series is a sequence of data points, measured at successive regular time intervals, in the case of astronomy generally over long periods of several months to several years. Time series are used in astronomy to record position or brightness of celestial objects in order to detect, for example, motion or periodicity. For instance, planetary transits can be detected by analyzing time series of stellar brightness measurements and looking for tiny periodic dips in the signal.
