我在这里报告如何使用引力波观测来确定哈勃常数 H0。在恒星合并之前，超紧凑双中子星双星系统的衰变轨道发出的近乎单色的引力波很可能被目前正在设计的千米大小的干涉引力波天线探测到1-4。该信号很容易识别，并且包含足够的信息来确定到双星的绝对距离，而与任何关于恒星质量的假设无关。十个达到 100 Mpc 的事件可能足以将哈勃常数测量到 3% 的精度。
I report here how gravitational wave observations can be used to determine the Hubble constant,H0. The nearly monochromatic gravitational waves emitted by the decaying orbit of an ultra–compact, two–neutron–star binary system just before the stars coalesce are very likely to be detected by the kilometre–sized interferometric gravitational wave antennas now being designed1–4. The signal is easily identified and contains enough information to determine the absolute distance to the binary, independently of any assumptions about the masses of the stars. Ten events out to 100 Mpc may suffice to measure the Hubble constant to 3% accuracy.
