展示了使用高级 LIGO 和高级 Virgo 探测器第三次观测运行的数据，搜索来自 20 个吸积毫秒 X 射线脉冲星的连续引力波的搜索结果，这些脉冲星具有精确测量的自旋频率和轨道参数。搜索算法使用隐马尔可夫模型，其中转移概率允许频率根据无偏随机游走漂移，而 $\mathcal{J}$ 统计最大似然匹配滤波器跟踪二元轨道相位。针对每个目标搜索三个窄子带，以测量的自旋频率的谐波为中心。搜索产生 16 个候选，与每个子带和搜索目标的误报概率为 30% 一致。这些候选者，以及针对 SAX J1808.4$-$3658 进行的额外机会目标搜索中的一个候选者（在一个月的观测运行期间爆发）不能确信与已知噪声源相关联。额外的后续行动并未提供令人信服的证据证明任何信号都是真正的天体物理信号。当所有候选者都假设为非天体物理时，上限设置为 95% 置信度下可检测到的最大波应变 $h_0^{95\%}$。最严格的约束是 IGR J17062$-$6143 中的 $h_0^{95\%} = 4.7\times 10^{-26}$。对每个目标可检测波应变的约束导致对中子星椭圆率和$r$模振幅的约束，其中最严格的分别是$\epsilon^{95\%} = 3.1\times 10^{-7}$和$\alpha^{95\%} = 1.8\times 10^{-5}$。这项分析是迄今为止对吸积毫秒 X 射线脉冲星连续引力波最全面、最灵敏的搜索。
Results are presented of searches for continuous gravitational waves from 20 accreting millisecond X-ray pulsars with accurately measured spin frequencies and orbital parameters, using data from the third observing run of the Advanced LIGO and Advanced Virgo detectors. The search algorithm uses a hidden Markov model, where the transition probabilities allow the frequency to wander according to an unbiased random walk, while the $\mathcal{J}$-statistic maximum-likelihood matched filter tracks the binary orbital phase. Three narrow sub-bands are searched for each target, centered on harmonics of the measured spin frequency. The search yields 16 candidates, consistent with a false alarm probability of 30% per sub-band and target searched. These candidates, along with one candidate from an additional target-of-opportunity search done for SAX J1808.4$-$3658, which was in outburst during one month of the observing run, cannot be confidently associated with a known noise source. Additional follow-up does not provide convincing evidence that any are a true astrophysical signal. When all candidates are assumed non-astrophysical, upper limits are set on the maximum wave strain detectable at 95% confidence, $h_0^{95\%}$. The strictest constraint is $h_0^{95\%} = 4.7\times 10^{-26}$ from IGR J17062$-$6143. Constraints on the detectable wave strain from each target lead to constraints on neutron star ellipticity and $r$-mode amplitude, the strictest of which are $\epsilon^{95\%} = 3.1\times 10^{-7}$ and $\alpha^{95\%} = 1.8\times 10^{-5}$ respectively. This analysis is the most comprehensive and sensitive search of continuous gravitational waves from accreting millisecond X-ray pulsars to date.
