论文摘要
在开发有效的一体模型的几个进步的基础上，用于与单个质量$（M_1，M_2）$的旋转一致的偏心二进制文件，我们引入了一种新的EOB波形模型，旨在描述大型质量比率策略中的灵感二进制模型，$ m_1 \ gg gg gg gg m_2 $。 The model exploits the current state-of-the-art TEOBResumS-Dali model for eccentric binaries, but the standard EOB potentials $(A,\bar{D},Q)$, informed by Numerical Relativity (NR) simulations, are replaced with the corresponding functions that are linear in the symmetric mass ratio $ν\equiv m_1 m_2/(m_1+m_2)^2$ taken以8.5pn的精度。为了改善其强场行为，这些功能是：（i）使用PADé近似物适当地分解和重新定义，（ii）另外有效地告知通过引力自我强制理论（GSF）获得的最新数值结果。为简单起见，该模型的自旋领域被视为teobresums-dali，尽管删除了NR信息的自旋轨道有效校正。我们将当前的GSF信息EOB框架作为一种概念上完整的分析工具，以生成用于偏心极端（和中间）质量比的波形，用于未来的重力波检测器。
Building upon several recent advances in the development of effective-one-body models for spin-aligned eccentric binaries with individual masses $(m_1,m_2)$ we introduce a new EOB waveform model that aims at describing inspiralling binaries in the large mass-ratio regime, $m_1\gg m_2$. The model exploits the current state-of-the-art TEOBResumS-Dali model for eccentric binaries, but the standard EOB potentials $(A,\bar{D},Q)$, informed by Numerical Relativity (NR) simulations, are replaced with the corresponding functions that are linear in the symmetric mass ratio $ν\equiv m_1 m_2/(m_1+m_2)^2$ taken at 8.5PN accuracy. To improve their strong-field behavior, these functions are: (i) suitably factorized and resummed using Padé approximants and (ii) additionally effectively informed to state-of-the-art numerical results obtained by gravitational self-force theory (GSF). For simplicity, the spin-sector of the model is taken to be the one of TEOBResumS-Dali, though removing the NR-informed spin-orbit effective corrections. We propose the current GSF-informed EOB framework as a conceptually complete analytical tool to generate waveforms for eccentric Extreme (and Intermediate) Mass Ratio Inspirals for future gravitational wave detectors.
