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.
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过程中的共振序列，并表明只有两种可能的结果，每种结果在波形上都有独特的印记。如果云与双星几乎反向旋转，那么云会保持其原始状态，直到它进入未来引力波探测器（如激光干涉空间天线）的灵敏度频段。在所有其他情况下，共振会破坏云，同时驱使双星与其一起共转，且其偏心率接近一个固定点。这为从大量黑洞双星的统计分析中推断新玻色子的存在开辟了可能性。
