Astronomers are surprised when a black hole “belches” a star

Astronomers were amazed when a Black hole The star that consumed it three years ago erupts, according to a new study analyzing galactic events.

The study, published in the Astrophysical Journal last week, details how scientists saw a black hole engulf a tiny star located 665 million light-years from Earth. However, in June 2021, the same black hole begins to eject ongoing material light speed.

“This really surprised us: no one has ever seen anything like it before,” said Yvette Sindez, co-author of the study and associate researcher at the Center for Astrophysics. Harvard and Smithsonian.

“It’s as if this black hole suddenly started spitting out a lot of material from the star that ate it years ago,” Sindis added.

Data from the Very Large Array in New Mexico told researchers that the black hole had reappeared, but the team did not know why its outflow was delayed for three years. Sendes likened the activity of the black hole to “burping” after a meal.

“This is the first time we’ve seen such a long delay between feeding and outflow,” said Ido Berger, another co-author of the study. “The next step is to explore whether this is actually happening more regularly and we haven’t seen EFT late enough in its development.”

TDE means Tidal turbulence events It describes the process by which a star is consumed by a black hole. The researchers, who dubbed the black hole “AT2018hyz”, collected observations using a variety of techniques, including the ALMA Observatory in Chile, the MeerKAT in South Africa, the Australian Telescope Compact Array in Australia and the Observatory a Chandra X-rays.

Black holes are thought to arise from the remains of a huge dead star. This area has the ability to consume anything and attract all substances, including light.
