Computer Simulations Revealed That Milky Way Catapults Stars in the Outer Halo

The researchers have proven that the clusters of supernovas are responsible for the creation of scattered stars, which represent suns that orbit in an unconventional way in the outer stellar halos of the Milky Way galaxy. Therefore, this discovery is offering researchers a proper insight into the formation and evolution of stars systems over the past billion years.

The Feedback in Realistic Environments 2 research has provided scientists with self-consistent information regarding the disruptions in the galactic rotations. The study was recently published in the Monthly Notices of the Royal Astronomical Society journal, cited on EurekAlert.

The numerical data have demonstrated that the Milky Way is highly probable to launch stars into the circumgalactic space. This occurrence creates the danger of triggering supernova explosions, as reported by the dean of UCI’ School of Physical Sciences, Professor James Bullock.

What is even more interesting is the dying process of stars, which creates an enormous amount of energy expelled in the galaxy. Up until now, it was commonly believed that the galaxies that were assembled during intense periods are more likely to eject a couple of stars into distant orbits.

The study has shown researchers that the stars are prone to create outflows which start from their galactic centers and go to their halos. The research included comparing data regarding the 3D velocity of stars that was analyzed by the European Space Agency during the Gaia mission. The results showed that there are similar structures that bear a resemblance to the outflow stars.

During the life of the Milky Way galaxy, the amount of stars produced by the supernova bubble is around two percent of the total number of the stars present in the Universe. Researchers are still trying to understand how the ejection process occurs. The project was sponsored by the National Science Foundation in collaboration with the Heising-Simons Foundation.
