标题： Proposed New Test of Spin Effects in General Relativity

摘要： 最近发现的双脉冲星PSR J0737-3039A/B为首次无可争议地观察广义相对论中的自旋效应提供了机会。 现有的研究涉及检测自旋物体本身的进动。 然而，对于一个紧密的双星系统，自旋效应对轨道的影响也可能被察觉。 它们不仅会增加近日点的进动（其量值与传统贡献相比很小），还会导致轨道绕自旋方向的进动。 测量这种效应还可以提供关于脉冲星转动惯量的信息。 显示英文摘要

摘要： The recent discovery of a double-pulsar PSR J0737-3039A/B provides an opportunity of unequivocally observing, for the first time, spin effects in general relativity. Existing efforts involve detection of the precession of the spinning body itself. However, for a close binary system, spin effects on the orbit may also be discernable. Not only do they add to the advance of the periastron (by an amount which is small compared to the conventional contribution) but they also give rise to a precession of the orbit about the spin direction. The measurement of such an effect would also give information on the moment of inertia of pulsars.
