Astronomers Discover First Binary Star System Near Milky Way's Supermassive Black Hole
The D9 binary system challenges assumptions about extreme gravitational environments and offers new insights into the galactic center.
- Researchers have identified a binary star system, named D9, orbiting near Sagittarius A*, the supermassive black hole at the center of the Milky Way.
- This marks the first confirmed detection of a binary star system in such a high-gravity environment, overturning previous beliefs about their instability near black holes.
- D9 is estimated to be 2.7 million years old and is expected to merge into a single star within about a million years due to the black hole's gravitational forces.
- The discovery sheds light on the mysterious G objects in the S cluster, which may be remnants of merged binary stars or unmerged systems like D9.
- Astronomers suggest this finding opens the possibility of detecting planets in the galactic center, as planets often form around young stars like those in D9.
