Dynamical boson stars

Abstract The idea of stable, localized bundles energy has strong appeal as a model for particles. In the 1950s, John Wheeler envisioned such smooth configurations electromagnetic that he called geons , but none were found. Instead, particle-like solutions found in late 1960s with addition scalar field, and these given name boson stars . Since then, find use wide variety models sources dark matter, black hole mimickers, simple binary systems, tool finding holes higher dimensions only single Killing vector. We discuss important varieties stars, their dynamic properties, some uses, concentrating on recent efforts.
