A black hole in the galaxy, the color of the nearby stars largely changed

According to the theory, the black hole launched a powerful jet of gas, which cut through the outer layers of the red giants of the galaxy, which removed the red part of the star, resulting in the star becoming hotter and fainter. This is the belief of the Polish Academy of Sciences of Warsaw astrophysicist, Mitchell Zazaek, who published this theory on 12 November in the Astrophysical Journal.

No powerful jets of gas have come from Sagittarius these days, but two large bubbles of gas emitting gamma-rays sit above and below the galaxy, possibly evidence of powerful jets causing red spheres near it. Loss of their outer layer 4 million years ago.

“Jets operate on large red giants,” Zazak said. “They can be effectively reduced by jets.”

Zazaek says the Red Giant Stars are more sensitive than the others in these jets because of how big they are. This type of star forms when the center of a small star is filled with helium that it can no longer burn its hydrogen fuel and instead burns the hydrogen in the layer around the center. This causes the outer layer of the star to expand, causing the surface to cool and turn red. The resulting size makes red spheres the main target for Sagittarius A *-like jets.

Just as these red giants orbit Sagittarius A *, they tear apart the outer layer and describe it hundreds or thousands of times before it turns red-blue. His team has calculated that the jet is most effective in stripping the outer layer of red giants within 13 light years of a black hole.

Tuan Do, an astronomer at the University of California, Los Angeles, says, however, that “a combination of many such methods can be taken to fully explain the lack of red spheres,” according to Science News. He says it’s probably something other than a jet that lacks the red giants farther away from the black hole.

Both Doo and Zazaek theorize that it is probably the work of a large disk of gas that orbited a black hole millions of years ago. As the red spheres orbited the black hole, they probably said that they were seen passing through the disk and cut off their outer layers in the gas process of the disk.
