摘要
本文计算了赤道面自偶时空中大地轨道的频率,并得到了环量子参数P对偏心极质量比吸气中能量通量和角动量通量的先导效应。采用改进的 "解析-克鲁吉 "方法,对不同偏心率下的引力波形进行了计算。我们计算了 LISA 探测器的波形失配和环量子参数的测量误差。与太阳系的弱场实验相比,对 P 的约束能力将提高 3 到 10 倍。
Gravitational waves for eccentric extreme mass ratio inspirals of self-dual spacetime
In this paper, we calculate the frequencies of geodesic orbits in self-dual spacetime on the equatorial plane and obtain the leading-order effects of loop quantum parameters P on the energy flux and angular momentum flux in eccentric extreme mass ratio inspirals. The gravitational waveform under different eccentricity is carried out by improved “analytic-kludge” method. We calculate the waveform mismatches for the LISA detector and the measurement error on loop quantum parameters. The constraint capability on P will be improved by a factor of 3 to 10, compared to the weak field experiments in the solar system.
期刊介绍:
Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
