摘要: We study properties of boson stars consisting ultra-light scalar dark matter with repulsive self-interactions. investigate the origin maximum mass spherically symmetric stable which emerges only when solving full equations motion in curved space-time, but not approximated Schr\"odinger-Newton equations. When repulsion is weak, backreaction curvature on scalars acts as an additional source attraction and can overcome repulsion, resulting a star compactness. also point out that potential UV completed particle physics model light generally more complicated than widely used $\phi^4$ interaction. Additional interactions beyond dramatically change well modify prospect LIGO gravitational wave detection for binary mergers stars.
