论文摘要
我们提出了一种新的方法，可以检查丽莎带中是否形成了银河系双中性恒星二进制。在我们的方法中，我们为丽莎检测到的每个双中性星二进制二进制二进制二进制分配了有效的时间分数$τ$。该部分是观察到的轨道周期和偏心率的函数，在没有带内二元形成的情况下应均匀分布。将统计技术（例如Kolmogorov-Smirnov测试）应用于$τ$的实际列表，我们可以检查带式二进制组的签名。我们讨论了这种方法的前景，密切关注了1MHz约1MHz的银河系双中性星星二进制的可用样本数量。
We propose a novel method to examine whether Galactic double neutron star binaries are formed in the LISA band. In our method, we assign an effective time fraction $τ$ to each double neutron star binary detected by LISA. This fraction is given as a function of the observed orbital period and eccentricity and should be uniformly distributed in the absence of in-band binary formation. Applying statistical techniques such as the Kolmogorov-Smirnov test to the actual list of $τ$, we can inspect the signature of the in-band binary formation. We discuss the prospects of this method, paying close attention to the available sample number of Galactic double neutron star binaries around 1mHz.
