论文摘要

通过诉诸韦森霍夫流体建模的尼顿后源的引力波的产生,在纽约后的第一个后纽顿级的背景下,通过诉诸于Blanchet-Damour的形式,在爱因斯坦 - 卡丹理论的背景下进行了研究。在阐明了爱因斯坦 - 卡丹框架中流体动力学的基本原理后,我们研究了牛顿后近似方案中的Weyssenhoff液体。基本动力学方程的复杂性表明,通过点粒子极限采用离散描述,该过程允许分析灵感旋转的紧凑型二进制文件。然后,我们通过考虑二进制中子星系来提供结果的第一个应用。

The generation of gravitational waves from a post-Newtonian source endowed with a quantum spin, modeled by the Weyssenhoff fluid, is investigated in the context of Einstein-Cartan theory at the first post-Newtonian level by resorting to the Blanchet-Damour formalism. After having worked out the basic principles of the hydrodynamics in Einstein-Cartan framework, we study the Weyssenhoff fluid within the post-Newtonian approximation scheme. The complexity of the underlying dynamical equations suggests to employ a discrete description via the point-particle limit, a procedure which permits the analysis of inspiralling spinning compact binaries. We then provide a first application of our results by considering binary neutron star systems.
