Milky Way could be Catapulting Stars into its Outer Halo

Milky Way could be catapulting stars into its outer halo, UCI astronomers say

Findings may change fundamental thinking about star system formation, dynamics. University of California, Irvine astronomers and others have shown that clusters of supernovas can cause the birth of scattered, eccentrically orbiting suns in outer stellar halos, upending commonly held notions of how star systems have formed and evolved over billions of years.

Hyper-realistic, cosmologically self-consistent computer simulations from the Feedback in Realistic Environments 2 project enabled the scientists ...
