Scientists abnormal behavior was detected one of the brightest stars in the sky - Betelgeuse. According to scientists, the star may have a companion similar to our Sun. The study suggests that this could explain the sudden changes in brightness that have previously puzzled astronomers.
Betelgeuse, which is about 700 light years from Earth, is known for its instability. In 2019, the star suddenly lost much of its brightness, which led to speculation about a possible supernova explosion. However, new data suggest another reason — the presence of a stellar companion. Such a companion could affect the material surrounding Betelgeuse, causing periodic eclipses that lead to changes in brightness.
The researchers used numerous observations and computer models to study the dynamics of the star. They suggest that Betelgeuse may be part of a binary system with a second, less massive star orbiting it. This hypothesis explains the sudden changes in brightness that were previously a mystery to astronomers. Although scientists do not yet have direct evidence for the existence of a companion, their models match existing observations.
Alternatively, Betelgeuse's possible companion could be a Sun-like star. This assumption changes the view of the processes occurring in massive star systems and adds a new aspect to the study of the evolution of red supergiants. Binary star systems are quite common in the universe, and the study of such systems can help to better understand how the interaction of stars affects their evolution and the final stages of life.
