Building upon several recent advances in the developmentof effective-one-body (EOB) models for spin-aligned eccentric binaries with individual masses $(m_1,m_2)$, we introduce a new EOB waveform model that aims at describing inspiraling 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 $(A,\overline{D},Q)$, informed by numerical relativity (NR) simulations, are replaced with the corresponding functions that are linear in the symmetric mass ratio $\nu \equiv m_1{m}_2/(m_1+m_2{)}^2$ taken at 8.5PN (Post-Newtonian) 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.

面向非进动、偏心、大质量比 inspirals 的重力自力通知有效单体波形模型

建立在开发有效单体 (EOB) 模型的几项最新进展的基础上，该模型用于具有单独质量的自旋对齐偏心双星$({米}_1,{米}_2)$，我们引入了一种新的 EOB 波形模型，旨在描述大质量比状态下的鼓舞人心的二进制文件，${米}_1\gg {米}_2$. 该模型利用当前最先进的TEOBResumS-DALI模型用于偏心双星，但标准 EOB 电位$(\mathrm{一个},\overline{D},问)$，通过数值相对论 (NR) 模拟，被替换为在对称质量比中呈线性的相应函数$\nu \equiv {米}_1{米}_2/({米}_1+{米}_2{)}^2$以 8.5PN（后牛顿）精度拍摄。为了改善它们的强场行为，这些函数 (i) 使用 Padé 近似值对这些函数进行了适当的分解和恢复，并且 (ii) 还有效地告知了通过引力自力理论 (GSF) 获得的最新数值结果。为简单起见，模型的自旋扇区被视为TEOBResumS-DALI之一，尽管去除了 NR 通知的自旋轨道有效校正。我们建议将当前基于 GSF 的 EOB 框架作为概念上完整的分析工具，为未来的引力波探测器生成偏心极端（和中间）质量比的波形。
