light curves

A light curve is a graph that shows how the brightness of an astronomical object, like a star or planet, changes over time. By plotting these changes, scientists can study phenomena such as star variability, exoplanet transits, or supernova explosions. The shape and patterns in the light curve provide valuable information about the object’s properties, behavior, and environment. For example, a dip in brightness might indicate a planet passing in front of the star. Light curves are essential tools for understanding the dynamic universe through careful measurement of light over periods ranging from seconds to years.
