light curve
A light curve is a graph that shows how the brightness of an object, like a star or a planet, changes over time. By plotting the light measured at different moments, astronomers can identify patterns or events, such as when a star dims due to a planet passing in front of it or when a star explodes as a supernova. Light curves are crucial for understanding the properties and behaviors of celestial objects, helping scientists gather insights about their composition, distance, and life cycles.

A light curve is a graph that shows how the brightness of an object, like a star or a planet, changes over time. By recording the light emitted from these celestial bodies, astronomers can observe patterns or fluctuations that reveal important information about their properties. For example, a star that dims and brightens periodically may indicate it has a planet orbiting it. Light curves are essential for studying various astronomical phenomena, helping us understand the life cycles of stars, the presence of exoplanets, and even the dynamics of supernovae.
