Light curves are graphical representations of the brightness of an astronomical object over time, crucial for understanding the properties and behavior of celestial bodies like stars, exoplanets, and supernovae. By analyzing light curves, astronomers can infer details such as an object's rotation period, orbit, and even the presence of other celestial bodies through phenomena like eclipses or transits.

Brightness of an astronomical object

Celestial bodies are natural physical entities found in the universe, including stars, planets, moons, asteroids, comets, and meteoroids. They are studied to understand the formation, structure, and evolution of the universe, as well as the potential for life beyond Earth.

Stars

Exoplanets are planets that orbit stars outside our solar system, providing crucial insights into planetary formation and the potential for life beyond Earth. Their study involves detecting and characterizing these distant worlds to understand their atmospheres, compositions, and potential habitability.

Exoplanets

Supernovae are powerful and luminous stellar explosions that occur at the end of a star's life cycle, either through the collapse of a massive star or the accumulation of matter on a white dwarf. These events are crucial for the creation and distribution of heavy elements in the universe, influencing galactic evolution and serving as important tools for measuring cosmic distances.

Analyzing light curves

The rotation period of an astronomical object is the time it takes to complete one full spin around its axis. This period can vary greatly among different celestial bodies and is crucial for understanding their dynamics and physical properties.

Rotation Period

An orbit is the gravitationally curved trajectory of an object around a point in space, typically a star, planet, or moon. It results from the balance between the object's forward momentum and the gravitational pull of the central body, forming an elliptical path according to Kepler's laws of planetary motion.

Presence of other celestial bodies

Eclipses are astronomical events where one celestial body moves into the shadow of another, temporarily obscuring it from view. They occur in predictable cycles and can be classified mainly into solar and lunar eclipses, each with distinct characteristics and viewing conditions.
