“…Neutron stars of course have a surface at which the fluid density is discontinuous, as discussed for example in [99, 101]. In contrast, the scalar field that constitutes the boson star is smooth everywhere and lacks a particular surface.…”

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

“…One difference of consequence concerns the stellar surface. Neutron stars of course have a surface at which the fluid density is discontinuous, as discussed for example in Gundlach and Leveque ( 2011 ), Gundlach and Please ( 2009 ). In contrast, the scalar field that constitutes the boson star is smooth everywhere and lacks a particular surface.…”
