Superradiant clouds of ultralight bosons can leave an imprint on the gravitational waveform of black hole binaries through “ionization” and “resonances.” We study the sequence of resonances as the binary evolves and show that there are only two possible outcomes, each with a distinct imprint on the waveform. If the cloud and the binary are nearly counterrotating, then the cloud survives in its original state until it enters the sensitivity band of future gravitational wave detectors, such as the Laser Interferometer Space Antenna. In all other cases, resonances destroy the cloud while driving the binary to corotate with it and its eccentricity close to a fixed point. This opens up the possibility of inferring the existence of a new boson from the statistical analysis of a population of black hole binaries.

黑洞双星上玻色子云的遗产


超轻玻色子的超辐射云可以通过“电离”和“共振”在黑洞双星的引力波形上留下印记。我们研究了双星演化时的共振序列，结果表明只有两种可能的结果，每种结果在波形上都有不同的印记。如果云和双星几乎反向旋转，那么云将以其原始状态存在，直到它进入未来引力波探测器（例如激光干涉仪空间天线）的敏感带。在所有其他情况下，共振会破坏云，同时驱动双星与其一起旋转，并且其偏心率接近固定点。这开辟了从黑洞双星群体的统计分析中推断新玻色子存在的可能性。
