Astronomers have discovered strange objects in the center of our galaxy, possibly a new hybrid star type
A new class of strange objects in the center of our galaxy, not far from the central “Sagittarius A* ” black hole, have been discovered by American astronomers.
These objects, called G, “look like gases and behave like stars,” according to scientists.
The G’s are curiously volatile, as they are usually like stars, but when their orbits bring them close to the black hole, they stretch and “overflow” like Tiramola or chewing gum. This is probably a new hybrid type of star, unknown up until now.
Researchers at the University of California at Los Angeles (UCLA) have published this in the journal, Nature.
Six G objects have been found so far and, according to astrophysics professor Andrea Gates, all were once giant double stars (one orbiting the other), which were once merged due to the strong gravitational effect of “Sagittarius A*”. Now some of them seem to leak their mass to the black hole every time they approach it, so they change their shape.
The first object G1 was discovered in 2005 and was then considered an astronomical anomaly until G2 was found in 2012. Now, after the discovery of G3, G4, G5 and G6 and after 13 years of observations with the Hawaii Keck telescope, scientists can speak of not an abnormality but of a new class of objects in space whose exact nature is under investigation.
Objects G are just a few light months away from the central black hole, while Earth is about 26,000 light years away in the “outskirts” of our galaxy.
