Supernova explosions shoot super-fast stars across the galaxy

Supernova explosions are the culprits that cause super-high-flying stars to fly through galaxies.

Scientists from the University of Cambridge, UK, in a study published in the journal Monthly Notices of the Royal Astronomical Society, said the hypervelocity stars in the Milky Way were shot by supernova explosions from the old galaxy. Newsweek reported on July 5.

Previous science cannot explain why super-speed stars in the Milky Way reach speeds of over 3.2 million km / h. Suppose these stars were pulled out of the center of the Milky Way by the black hole, because in 2016, scientists discovered that the two-star system orbits each other at extremely fast speeds, even if not near any black hole.

The idea that supernovae separate from dwarf galaxies and chaotic star clusters cannot explain how these stars appear to be in the same position in the sky."Super-speed stars are mostly found in the constellations of Lion and Luc Fong . We wonder why," said Douglas Boubert, the study's lead author.

Using data from the SDSS observation station and computer simulation, the scientists determined that most super-speed stars are likely to come from the Large Magellanic Cloud (LMC) , the largest dwarf galaxy and the fastest turning around. the Milky Way at about 1.45 million km / h.

Super-speed stars are mostly found in the constellations of the Lion and the Lucidus.

According to the researchers, double stars in LMC revolve around each other at high speeds. When one of the stars exploded in a supernova explosion, the other star was shot into space at a tremendous speed formed from the speed of the LMC and the speed was shot.

"These stars jump off an express train, so they are not surprised why they fly so fast," co-author Rob Izzard said. "This also explains their position in the sky. They were shot along the LMC's trajectory in the south towards the constellations of the Lion and the Six Stool in the north."

Researchers hope data from the European Space Agency's Gaia satellite will confirm the study next year.
