稳定、局域能量束的想法作为粒子模型具有很强的吸引力。 20 世纪 50 年代，约翰·惠勒 (John Wheeler) 将这种束设想为电磁能的平滑结构，他将其称为“geons”，但最终没有找到。相反，在 20 世纪 60 年代末，人们发现了添加了标量场的类粒子解，这些解被命名为纳姆玻色子星。从那时起，玻色子星在各种模型中得到应用，作为暗物质的来源，作为黑洞模仿者，在双星系统的简单模型中，以及作为仅用单个杀伤矢量寻找更高维度黑洞的工具。我们讨论了玻色子星的重要种类、它们的动态特性以及它们的一些用途，重点关注最近的努力。
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 calledgeons, 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 nameboson 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.
