标题： Gravitational waves from double white dwarfs

摘要： 双白矮星可能是基于空间的引力波探测器如OMEGA和LISA的重要来源。 我们使用种群合成来预测银河系中当前的双白矮星种群以及该种群产生的引力波。 我们模拟了一个详细的功率谱，观测时间为10^6秒。在频率低于约3 mHz时，混乱限制噪声占主导地位。 在较高频率下，数千个双白矮星可以被单独分辨。 在我们的计算中包括包含中子星和黑洞的紧凑双星，会得到另外几百个被分辨的双星，以及一些十对可以在低频下高于双白矮星噪声被探测到的双星。 我们发现其中一颗白矮星向另一颗白矮星转移物质的双星非常稀少，因此对引力波探测器不重要。 我们讨论了不确定性，并将我们的结果与其他作者的结果进行了比较。 显示英文摘要

摘要： Double white dwarfs could be important sources for space based gravitational wave detectors like OMEGA and LISA. We use population synthesis to predict the current population of double white dwarfs in the Galaxy and the gravitational waves produced by this population. We simulate a detailed power spectrum for an observation with an integration time of 10^6 s. At frequencies below ~3 mHz confusion limited noise dominates. At higher frequencies a few thousand double white dwarfs are resolved individually. Including compact binaries containing neutron stars and black holes in our calculations yields a further few hundred resolved binaries and some tens which can be detected above the double white dwarf noise at low frequencies. We find that binaries in which one white dwarf transfers matter to another white dwarf are rare, and thus unimportant for gravitational wave detectors. We discuss the uncertainties and compare our results with other authors.
