标题： Parameter estimation accuracies of Galactic binaries with eLISA

摘要： 我们研究了接近单频的引力波源通过未来类似eLISA的探测器进行参数估计的精度问题。 eLISA能够观测由白矮星、中子星或黑洞组成的紧凑双星轨道产生的数百万个此类信号，并且可以解析和估计其中数千个信号的参数，从而提供关于它们轨道动力学、形成率以及演化路径的关键信息。 利用Fisher矩阵分析，我们比较了不同任务设计方案的参数估计精度，这些方案由GOAT顾问团队定义，该团队负责评估类似eLISA任务的科学能力和技术问题。 显示英文摘要

摘要： We study parameter estimation accuracy of nearly monochromatic sources of gravitational waves with the future eLISA-like detectors. eLISA will be capable of observing millions of such signals generated by orbiting pairs of compact binaries consisting of white dwarf, neutron star or black hole and to resolve and estimate parameters of several thousands of them providing crucial information regarding their orbital dynamics, formation rates and evolutionary paths. Using the Fisher matrix analysis we compare accuracies of the estimated parameters for different mission designs defined by the GOAT advisory team established to asses the scientific capabilities and the technological issues of the eLISA-like missions.
