The Astrophysical Journal Supplement Series, ApJS, reported the discovery by a team of Chinese astronomers, based on the results of analyzing data obtained from China’s high-speed stars LAMOST and the GAIA 591 European Space Telescope, and that the stars of ” high speed “are very fast stars. You can leave your galaxy at any time. Among them, 43 stars could escape the gravitational limitations of the Milky Way and fly in the future in intergalactic space.

Researcher Li Enpei from the Chinese Astronomical Observatory of the Chinese Academy of Sciences points out that since the discovery of the first star in 2005 and until now, the number of these stars has reached more than 550 stars of this type.

For his part, researcher Lu Yujun from the Chinese Academy of Sciences says that high-speed stars can help people gain a deeper understanding of problems related to galactology, the environment surrounding black holes, and the structure of the Milky Way.

The researchers analyzed the chemical and kinetic properties of 591 stars and found that they are stars in the inner corona.

And the researcher Zhao Gang from the Chinese Academy of Sciences adds: “Its low mineralization indicates that most of the stellar halo arose as a result of the merger and decomposition of dwarf galaxies”, according to “Novosti”.
