Astronomers in the United States have found a new class of unusual celestial bodies in the center of our Milky Way galaxy.

These bodies look like gas, but their behavior is similar to that of stars, said Andrea Gies of the University of California, Los Angeles.

Jez explained, in a statement from the university, that her team announced in the current issue of the British journal “Nature” the discovery of 4 heavenly bodies that were not known until now, bringing the number of bodies of this type to 6.

The team of researchers also talks about a special layer of astronomical objects, and they indicated that the precise nature of these objects is not clear.

The first offense

A group of researchers, under the supervision of Jeez, found in 2005 the first object of this type of object, and they called it G1, and it rotates in the orbit of a giant black hole in the center of our galaxy, and comes very close to it, from time to time.

In 2012, another object was discovered by researchers under the direction of Stefan Gelsmann, of the German Max Planck Institute for Earth-based Physics of Garching, near Munich, near the center of the black hole.

“At the time of the next approaching time, G2 left a really rare footprint,” she said, adding: “We saw that before, and it didn’t look very strange, until he approached the black hole and expanded.”

Jez pointed out that this offense loses a large part of its gas, during which time it turns from a crime that is not striking much, as long as it remains away from the black hole, to a crime that extends a lot and is deformed upon its approaching big.

The Geez team has now found 4 more of these objects in the middle of the massive black hole at the center of the Milky Way, the ones they gave symbols from G3 to G6.

“We now have a grouping of G-bodies,” said researcher Anna Ciorlu, a colleague of Geez, adding that “it is not a matter of revealing the truth of a unique event like G2.”

Melting of bodies

Jeez suggests that these six bodies are fused together, or are double stars that still fuse together.

Although G2 lost its gaseous casing as it approached the black hole, it did not lose the thick dust casing inside the gas.

“There must be something that keeps it together and enables it to survive after meeting the black hole,” Siurlo said. “This is evidence of the presence of asteroid inside the G2.”

Geez justified this hypothesis that the tremendous power of a black hole’s gravitational pull could drive a fusion of a double star in the G-bodies.

At the same time, this group of celestial bodies is likely, according to the researchers, to have an effect on the activity of the center of the black hole, by feeding the hole with the gas that it swallows, every time it passes the hole.

“The substance that is extracted from it due to the tidal forces and the roots, when a speeding pass near the center of the black hole, does not find escape from falling into the black hole,” said Mark Morris, a Jiz classmate and study participant.

And when this happens, Morris added, the hole becomes able to produce massive fiery forms, because the heat that the black hole swallows rises strongly and emits a lot of radiation, before it disappears behind the event horizon.
