论文摘要
潮汐力可能会猛烈破坏位于星系中心的超级质量黑洞的恒星，导致耀斑在天空调查中被视为明亮的短暂事件。这些事件发生的速度取决于黑洞的旋转，而黑洞旋转又可能受到超光的超光玻色子的影响。我们对这些效果进行详细分析，并表明搜索恒星潮汐破坏具有揭示超光玻色子存在的重要潜力。特别是，我们发现Vera Rubin天文台对时空的遗产调查的即将到来的恒星潮汐破坏率测量可用于发现或排除群众的玻色子，范围从$ 10^{ - 20} $到$ 10^{ - 18} $ ev。我们的分析还表明，这些测量值可用于限制各种超级黑洞自旋分布，并确定是否优选近距离旋转。
Stars that pass close to the supermassive black holes located in the center of galaxies can be violently disrupted by tidal forces, leading to flares that are observed as bright transient events in sky surveys. The rate for these events to occur depends on the black hole spins, which in turn can be affected by ultra-light bosons due to superradiance. We perform a detailed analysis of these effects and show that searches for stellar tidal disruptions have a significant potential to uncover the existence of ultra-light bosons. In particular, we find that upcoming stellar tidal disruption rate measurements by the Vera Rubin Observatory's Legacy Survey of Space and Time can be used to either discover or rule out bosons with masses ranging from $10^{-20}$ to $10^{-18}$ eV. Our analysis also indicates that these measurements may be used to constrain a variety of supermassive black hole spin distributions and determine if close-to maximal spins are preferred.
