我们直接上限的引力波的振幅从28个孤立的射电望远镜的相干多探测器分析的数据收集在第二次科学运行的LIGO干涉探测器。这是28个卫星中26个卫星的第一个直接上限。我们首次使用协调的无线电观测来为预期的引力波信号建立无线电引导的相位模板。探测器前所未有的灵敏度使我们能够将应变上限设置为10（-24）的几倍。这些应变极限转化为赤道椭圆度的极限，对于四个最近的赤道椭圆度，其小于10（-5）。
We place direct upper limits on the amplitude of gravitational waves from 28 isolated radio pulsars by a coherent multidetector analysis of the data collected during the second science run of the LIGO interferometric detectors. These are the first direct upper limits for 26 of the 28 pulsars. We use coordinated radio observations for the first time to build radio-guided phase templates for the expected gravitational-wave signals. The unprecedented sensitivity of the detectors allows us to set strain upper limits as low as a few times 10(-24). These strain limits translate into limits on the equatorial ellipticities of the pulsars, which are smaller than 10(-5) for the four closest pulsars.
