Black holes “eject” the stars they once destroyed, but scientists don’t know why
Black holes throw out the remains of the stars they destroyed many years ago. Astronomers made such a discovery after years of observing black holes. It was called “space belch”, writes Space.com. “I call it a ‘burp’. After all, a certain amount of time passes after the black hole swallowed the star,” explained Yvette Sandes, one of the authors of the study. Scientists have observed black holes that participate in a phenomenon called “tidal collapse.” It happens when a star is too close to a black hole. As a result, the black hole rips the star apart and stretches it into a long strip of material that resembles spaghetti. Astronomers have discovered that 10 out of 24 black holes eject the remnants of stars after a few years. In the observation, scientists note that black holes regurgitate after 2 or 6 years. This means that they again “regurgitated” part of what they “swallowed”. However, astronomers had not detected such processes before, and this was an unexpected discovery for them. However, the study has not yet been peer-reviewed. Sandes added that at the moment his team cannot explain why black holes “eject” stellar matter after a few years. However, they will continue to watch for black holes that can gobble up stars. It will be recalled that earlier scientists from the National Institute of Astrophysics calculated the speed of cosmic winds emitted by supermassive black holes.
