标题： Excitation of high frequency voices from intermediate-mass-ratio inspirals with large eccentricity

摘要： 中子星质量致密天体与中等质量黑洞的合并，也被称为中等质量比吸积，通常不被认为是当前地基引力波探测器可行的引力波源，因为此类源的频率通常较低。 在本文中，我们采用有效单体形式作为运动方程，并通过在频域中求解Teukolsky方程获得准确计算的引力波波形。 我们指出，中等质量比吸积的大偏心率可以激发高频率的引力波模式。 这些高频率模式可以扩展到超过10 Hz，并进入Advanced LIGO和Advanced Virgo的设计灵敏度范围。 我们提出，这种高度偏心的中等质量比吸积可能成为可行的源，并可能被地基引力波探测器，如Advanced LIGO和Advanced Virgo观测到。 显示英文摘要

摘要： The coalescence of a stellar-mass compact object together with an intermediate-mass black hole, also known as intermediate-mass-ratio inspiral, is usually not expected to be a viable gravitational wave source for the current ground-based gravitational wave detectors, due to the generally lower frequency of such source. In this paper, we adopt the effective-one-body formalism as the equation of motion, and obtain the accurately calculated gravitational waveforms by solving the Teukolsky equation in frequency-domain. We point out that high frequency modes of gravitational waves can be excited by large eccentricities of intermediate-mass-ratio inspirals. These high frequency modes can extend to more than 10 Hz, and enter the designed sensitive band of Advanced LIGO and Advanced Virgo. We propose that such kind of highly eccentric intermediate-mass-ratio inspirals could be feasible sources and potentially observable by the ground-based gravitational wave detectors, like the Advanced LIGO and Advanced Virgo.
