The Place Where Eclipse Happened Every Three Days.
There is a star system that always dims in every 3 days.
Beta Persei, also known as Algol, is a fascinating example of a variable star. Its brightness fluctuates due to a unique phenomenon called eclipsing binary. Algol consists of two stars: a larger, brighter star known as Algol A, and a smaller, dimmer companion known as Algol B. From our perspective on Earth, Algol B periodically passes in front of Algol A, causing a partial eclipse.
This eclipse occurs roughly every 2 days, 20 hours, and 49 minutes, resulting in a predictable brightness variation. When Algol B is in front of Algol A, the combined brightness decreases, making Algol appear fainter. This phase is referred to as the primary eclipse. As Algol B moves away, the brightness returns to normal until the next eclipse occurs.
This regular variation in brightness makes Algol an essential target for astronomers studying eclipsing binaries. By observing the timing and depth of the eclipses, scientists can determine various properties of the stars, such as their sizes, masses, and orbits.
Algol's behaviour exemplifies the dynamic nature of celestial objects and provides valuable insights into stellar evolution and binary star systems. It's a reminder that even seemingly constant stars reveal complexities upon closer examination.
