An international team of researchers has made a groundbreaking discovery by finding the first binary star orbiting close to Sagittarius A*, the supermassive black hole at the center of our galaxy. This finding sheds light on stellar survival in extreme gravitational environments and opens possibilities for detecting planets near Sagittarius A*.
An international team of researchers has detected a binary star orbiting close to Sagittarius A* , the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been found in the vicinity of a supermassive black hole .
The discovery, based on data collected by the European Southern Observatory's Very Large Telescope (ESO's VLT), helps us understand how stars survive in environments with extreme gravity, and could pave the way for the detection of planets close to Sagittarius A*. 'Black holes are not as destructive as we thought,' says Florian Peißker, a researcher at the University of Cologne, Germany, and lead author of the study published today in. Binary stars, pairs of stars orbiting each other, are very common in the Universe, but they had never before been found near a supermassive black hole, where the intense gravity can make stellar systems unstable. This new discovery shows that some binaries can briefly thrive, even under destructive conditions. D9, as the newly discovered binary star is called, was detected just in time: it is estimated to be only 2.7 million years old, and the strong gravitational force of the nearby black hole will probably cause it to merge into a single star within just one million years, a very narrow timespan for such a young system. 'This provides only a brief window on cosmic timescales to observe such a binary system -- and we succeeded!' explains co-author Emma Bordier, a researcher also at the University of Cologne and a former student at ES
