论文摘要
从重力波观测到二进制中子星特性的推断需要数百万波形的产生，每个波形在频率范围内的三个幅度范围均大约三个。因此，波形模型必须有效地生成，同时，从牛顿后的准绝热灵感到合并制度。解决此问题的一个简单解决方案是将有效的一个体波形与固定相近似相结合，以获得从任何低频到合并有效的频域多极近似值。我们证明，在绝热后近似中产生的有效的一体频域波形是计算上具有现象学和替代模型（实际上）任意长的，并忠于任何二进制参数的合并。同样的方法也可以用来有效地生成可通过空间干涉仪检测到的中间质量二进制黑洞灵感波形。
The inference of binary neutron star properties from gravitational-wave observations requires the generation of millions of waveforms, each one spanning about three order of magnitudes in frequency range. Thus, waveform models must be efficiently generated and, at the same time, be faithful from the post-Newtonian quasi-adiabatic inspiral up to the merger regime. A simple solution to this problem is to combine effective-one-body waveforms with the stationary phase approximation to obtain frequency-domain multipolar approximants valid from any low frequency to merger. We demonstrate that effective-one-body frequency-domain waveforms generated in post-adiabatic approximation are computationally competitive with current phenomenological and surrogate models, (virtually) arbitrarily long, and faithful up to merger for any binary parameter. The same method can also be used to efficiently generate intermediate mass binary black hole inspiral waveforms detectable by space-based interferometers.
