The Milky Way expels stars outside the galaxy


“Irvine” groups of supernovae near the core of the Milky Way explode with such force as they release gas jets into outer space beyond the classic disc of our galaxy, according to a study conducted at the University of California, Irvine. The so-called “supernova reactions” can represent about 40% of these outer aura stars, while the total number of stars produced by the supernova bubbles is about 2% of the total galaxy.

Gas is expelled and cooled as stars form on the way out of the galaxy, leading to unusual or decentralized orbits that can interfere with the regular whirlpool of the Milky Way. These stars, which appear in an incredibly realistic computer simulation, flip our current understanding of the formation and evolution of the star system. “This high-res numerical simulation has shown that the Milky Way is likely to fire stars into the galactic space through outflows, caused by supernova explosions,” said the prepared James James Bullock.

“While the results are based on simulation, there is a large amount of observational evidence for star formation outside of galaxies,” the team added. Heaviest and richer stars in minerals, such as the sun, orbit the center of the galaxy at a predictable speed in a pattern that can also be assumed. “We found that as the center of the galaxy orbits, a bubble driven by supernova feeding develops, as stars form on its edge,” study leader Seiji Yu said. It looks as if the stars are being kicked out of the center. ”
