Double star D9: Scientists discover unique phenomenon in space!

German researchers have discovered a new double star system at the center of the Milky Way, which is called D9. This system circles a supermassed black hole, such as Welt.de . The discovery shows itself as a chance and as a stroke of luck and represents the only known double star system that moves around a black hole on a narrow orbit.

The black hole has the four million fold mass of the sun. So far, astronomers have believed that no stars can arise in the vicinity of such an object. Surprisingly, however, there are numerous stars that move around the black hole in a narrow area of ​​less than a light year. These stars reach speeds of several thousand kilometers per second, which requires a revision of the previous astronomical views.

Details for the discovery of D9

The research team observed G objects that appear like small clouds of gas and dust. The regular fluctuations in the speed of the star D9 finally led to the discovery of the double star system. D9 is made up of two stars with 2.8 and 0.7 times the sun mass. These circle with a circulation time of 372 days and a distance of about 1.5 times earth-sun distance.

It is particularly noticeable that the proximity of the black hole means that the stars approach each other and are expected to merge. D9 is about 2.7 million years old and will no longer exist in about one million years. The discovery could help to expand the understanding of the mysterious G objects in the Galactic Center. Researchers also hope to examine the creation of these stars in more detail with new instruments at the European South Sternhewarte (ESO) in Chile.

The internationally composed research team has published the results in the “Nature Communications” journal. As border-ripple-aktuell.de , the discovery of D9 in question that the gravitational forces of black holes endanger stabilizing star systems. This could revolutionize the understanding of the stability of stars in extreme gravitational environments.

References to gas and dust around D9 indicate that it is a very young star system, whereupon new questions about the nature of the G objects and the possibility of planet formation were raised by such stars. The researchers are optimistic that planets can be demonstrated in the Galactic Center.
