Light Curves, Spectra, and Images

Tools for All Astronomers

Astronomical data can be analyzed in different ways to learn about a particular source. Astronomers can time events (for instance, recording exactly when a binary star system is eclipsed and for how long), record the energy distribution of a source (for instance, passing sunlight through a prism to break it into its component colors), or record the appearance of a source (for instance, taking a picture of the source). These three methods are by no means exclusive of each other, but each reveals different aspects of a source and each method gives the astronomer slightly different information. These are called timing, spectral, and imaging analysis, respectively. The results of each are displayed as light curves, spectra, and images.
