While many theories about black holes in the universe, a study headed by Dr. Florian Pesker found a densely packed group of stars, called an S cluster, a complete circle around the black hole at the center of our galaxy. It only takes four years to make the rounds. ,
Yes that is correct! only four years.
cluster, called s cluster, is home to over a hundred stars that differ in their brightness and mass. S stars move especially fast.
The region around the black hole at the center of our galaxy is densely packed with clusters of stars.
Dr Florian Pesker, lead author of the new study, said: ‘A key member, S2, behaves like an older person sitting in front of you in a movie theatre: it blocks your view of what’s important. ‘The view at the center of our galaxy is therefore often obscure’ S2. However, in brief moments we can observe the surroundings of the central black hole.’
Through continuously sophisticated methods of analysis, coupled with nearly twenty years of observations, the scientist has now without a doubt identified a star that revolves around a central supermassive black hole in just four years. A total of five telescopes observed the star, four of these five were combined into a larger telescope to make even more precise and detailed observations.
“It was completely unexpected for a star to be in a stable orbit so close and fast around a supermassive black hole and it marks the limit to what can be observed with conventional telescopes,” Pesker said.
Furthermore, the discovery sheds new light on the origin and evolution of the fast-moving star’s orbit at the Earth’s center. Galaxy, ‘S4716’s short-period, compact orbit is quite puzzling,’ said Michael Zajcek, an astrophysicist at Masaryk University in Brno who was involved in the study.
Stars cannot form so easily near black holes. S4716 had to move inward, for example by approaching other stars and objects in the S cluster, causing its orbit to shrink significantly.’
