Black hole repeatedly tears star apart, but stellar survivor returns each time

Astronomers have discovered that some stars caught in the gravitational pull of supermassive black holes can survive repeated encounters, losing material in a series of fading light bursts before recovering and approaching again.

Black hole repeatedly tears star apart, but stellar survivor returns each time

In a phenomenon that challenges conventional understanding of stellar destruction, researchers have observed stars repeatedly torn apart by supermassive black holes, only to reform and return for another encounter. The process occurs as stars venture into the intense gravitational field surrounding these cosmic monsters, losing material in successive bursts of light that gradually diminish in intensity over time.

The key to stellar survival lies in the star's initial rotation speed, according to new research findings. When a star possesses rapid initial spin, this property constrains excessive rotation during subsequent close approaches to the black hole. This limitation proves crucial in determining whether a star can endure multiple encounters or faces complete destruction.

The gravitational dance between stars and supermassive black holes represents one of the most extreme interactions in the universe. As stars spiral closer to these objects, tidal forces progressively strip away their outer layers, triggering luminous outbursts visible from Earth. The repeated nature of these encounters suggests that certain stellar characteristics allow them to escape total annihilation.

These observations provide fresh insights into the dynamics of the galactic centres where supermassive black holes reside. Understanding how stars can survive such violent interactions expands knowledge of stellar physics and black hole behaviour, offering astronomers new perspectives on some of the universe's most dramatic phenomena.
