Star with shortest known orbital period discovered

A group of researchers has discovered the fastest known star, which reaches a speed of about 8,000 kilometers per second, which is why it has the shortest orbital period known so far.

The results of a study published by The Astrophysical Journalreport that researchers from the University of Cologne and Masaryk University in Brno, both in the Czech Republic, discovered the celestial object that travels around a black hole in record time.

As the study has revealed, the star, S4716, orbits Sagittarius A* (the black hole in the center of our Milky Way) in four years and reaches a speed of around eight thousand kilometers per second, HispanTV reports.

A total of five telescopes that observed the star have participated in the discovery; four of these five were combined into one large telescope to enable even more precise and detailed observations.

“For a star to be in a stable orbit so close and so fast in the vicinity of a supermassive black hole was completely unexpected and marks the limit of what can be observed with traditional telescopes,” Florian Peissker, the lead author of the study, said on Tuesday. study in a statement.

According to experts, the discovery sheds new light on the origin and evolution of the orbit of the fast-moving stars at the heart of the Milky Way.

“The compact short-period orbit of S4716 is quite puzzling,” he stated. Michael Zajacekastrophysicist at Masaryk University in Brno.
