论文摘要
低质量X射线二进制方法是通过基于地面干涉仪进行连续重力波搜索的主要目标。从搜索五个低质量X射线二进制文件中提出了结果，其旋转频率和轨道元素是从X射线脉动中准确测量的：Hete J1900.1-2455，IGR J00291+5934，SAX J1808.4-3658，sax J1808.4-3658，XTE J0929-314和j1414148148148。通过观察到高级激光干涉仪重力波观测站（LIGO）的观察2分析数据。搜索算法使用隐藏的马尔可夫模型来跟踪旋转徘徊，$ \ mathcal {j} $ - 统计最大似然匹配的过滤器以跟踪轨道阶段，以及一套五个否决权，以拒绝非高斯噪声中的伪像。该搜索产生了许多低音，高于阈值候选者，与所选的假警报概率一致。随后的观察跑步将在候选人中进行跟进。
Low mass X-ray binaries are prime targets for continuous gravitational wave searches by ground-based interferometers. Results are presented from a search for five low-mass X-ray binaries whose spin frequencies and orbital elements are measured accurately from X-ray pulsations: HETE J1900.1-2455, IGR J00291+5934, SAX J1808.4-3658, XTE J0929-314, and XTE J1814-338. Data are analysed from Observing Run 2 of the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO). The search algorithm uses a hidden Markov model to track spin wandering, the $\mathcal{J}$-statistic maximum likelihood matched filter to track orbital phase, and a suite of five vetoes to reject artefacts from non-Gaussian noise. The search yields a number of low-significance, above threshold candidates consistent with the selected false-alarm probability. The candidates will be followed up in subsequent observing runs.
