多个小组使用名为 SEOBNRE 的偏心双黑洞波形模型来分析 LIGO-Virgo 的引力波数据。通过与数值相对论的比较,验证了该模型的准确性。然而SEOBNRE是时域模型,生成波形的效率是数据分析的瓶颈。为了克服这个缺点,我们提供了一个基于 SEOBNRE 波形的偏心双黑洞的降阶代理模型。该替代模型 (SEOBNRE\_S) 可以足够精确地模拟完整的吸气-合并-振铃波,涵盖非自旋(自旋)双星的偏心率从 0 到 0.25 (0.1),质量比从 1:1 到 5:1 (2:1)。波形生成速度比原始 SEOBNRE 模型加快约 $10^2 \sim 10^3$ 倍。因此 SEOBNRE\_S 可能有助于分析 LIGO 数据以发现潜在的偏心率。
A waveform model for the eccentric binary black holes named SEOBNRE has been used to analyze the LIGO-Virgo's gravitational wave data by several groups. The accuracy of this model has been validated by comparing it with numerical relativity. However, SEOBNRE is a time-domain model, and the efficiency for generating waveforms is a bottleneck in data analysis. To overcome this disadvantage, we offer a reduced-order surrogate model for eccentric binary black holes based on the SEOBNRE waveforms. This surrogate model (SEOBNRE\_S) can simulate the complete inspiral-merger-ringdown waves with enough accuracy, covering eccentricities from 0 to 0.25 (0.1), and mass ratio from 1:1 to 5:1 (2:1) for nonspinning (spinning) binaries. The speed of waveform generation is accelerated about $10^2 \sim 10^3$ times than the original SEOBNRE model. Therefore SEOBNRE\_S could be helpful in the analysis of LIGO data to find potential eccentricities.
