论文摘要
我们回顾了由重力，所谓的玻色子星定位的复杂标量场的粒子样构型。在最简单的情况下，这些解决方案具有球形对称性，它们可能在带有全局$ u（1）$对称性的大量爱因斯坦 - 克莱因 - 戈登理论中出现，作为标量冷凝物的重力块。此外，还有具有非零角动量的轴向对称玻色子恒星，以及各种非平凡的多极固定构型，没有任何连续的对称性。在这个简短的概述中，我们讨论了玻色子恒星的重要动态特性，重点关注玻色子恒星多组分星座的最新结果。
We review particle-like configurations of complex scalar field, localized by gravity, so-called boson stars. In the simplest case, these solutions posses spherical symmetry, they may arise in the massive Einstein-Klein-Gordon theory with global $U(1)$ symmetry, as gravitationally bounded lumps of scalar condensate. Further, there are spinning axially symmetric boson stars which possess non-zero angular momentum, and a variety of non-trivial multipolar stationary configurations without any continuous symmetries. In this short overview we discuss important dynamic properties of the boson stars, concentrating on recent results on the construction of multicomponent constellations of boson stars.
