标题： Tests of strong-field gravity and gravitational radiation damping in binary-pulsar systems

摘要： 这次演讲回顾了双星脉冲星数据对引力理论的约束，特别是对"标量-张量"理论的约束，这些理论是广义相对论最自然的替代理论。 由于中子星具有很强的引力结合能，双星脉冲星实验在本质上不同于太阳系实验：它们能够探测在弱引力场条件下与广义相对论无法区分的模型。 除了系统B1913+16和B1534+12中最精确的两个双星脉冲星实验外，我们还介绍了由多个中子星-白矮星双星提供的广义相对论的各种"零"测试结果，尤其是引力辐射阻尼的测试。 [这篇非常短的论文的主要兴趣在于它的图表，该图表也考虑了"强等效原理"测试。] 显示英文摘要

摘要： This talk reviews the constraints imposed by binary-pulsar data on gravity theories, and notably on "scalar-tensor" theories which are the most natural alternatives to general relativity. Because neutron stars have a strong gravitational binding energy, binary-pulsar tests are qualitatively different from solar-system experiments: They have the capability of probing models which are indistinguishable from general relativity in weak gravitational field conditions. Besides the two most precise binary-pulsar experiments, in the systems B1913+16 and B1534+12, we also present the results of the various "null" tests of general relativity provided by several neutron star-white dwarf binaries, notably those of gravitational radiation damping. [The main interest of this very short paper is its figure, which also takes into account the "strong equivalence principle" tests.]
