A black hole in the galaxy apparently changed the color of stars in the area

According to astrophysicists, the supermassive black hole known as Sagittarius A * in the Milky Way has apparently changed the color of stars in the environment. , but it has fewer red giant stars than expected, and according to a new report from Science News, astrophysicists believe that Sagittarius A * is the culprit.

According to the theory, the black hole launched a powerful jet of gas that tore off the outer layers of the galaxy’s red giants, which saw the red part of the star removed as the star became hotter and bluer as a result. This is the conviction of the Polish Academy of Sciences in the Astrophysicist of Warsaw, Michal Zajaček, who published this theory in the Astrophysical Journal on 12 November.

There are no powerful gas jets coming from Sagittarius these days, but above and below the middle of the Milky Way are two large bubbles of gamma ray gas emitting. This is a possible proof of the powerful ray that causes red giants near it to lose their outer layer 4 million years ago.

“The jet aircraft prefers to respond to large red giants,” Zajaček said. “They can be effectively removed by the jet.”Zajaček says red giant stars are more vulnerable than others to such rays because of their size. This type of star is formed when the center of smaller stars becomes so full of helium that it can no longer burn its hydrogen fuel, but burns the hydrogen in a layer around the center. This causes the star’s outer layer to expand, which in turn causes the surface to cool and turn red. The resulting size makes red giants a primary target for jets such as those of Sagittarius A *.

As these red giants revolve around Sagittarius A *, they must pass through the ray described by Zajaček hundreds or thousands of times before the outer layer is torn away and the red turns blue. His team calculates that the beam is most effective at tearing the outer layer of red giants within .13 light-years from the black hole.

According to the astronomer Tuan Do of the University of California, Tuan Do, he believes that it “may require a combination of different types of mechanisms to fully explain the lack of red giants,” according to Science News. He says it was probably something other than a jet that caused the lack of red giants further away from the black hole.Both Do and Zajaček theorize that it may be the work of a large disk of gas that surrounded the black hole millions of years ago. As the red giants revolved around the black hole, they probably passed through the disk, and the gas from the disk possibly tore off their outer layers in the process.
