具有典型磁矩的中子双星系统中引力波向电磁波的转化
发布时间：2021-04-19 09:32
引力波是爱因斯坦广义相对论的直接推论，对引力波的检测，是对广义相对论最有效和最严格的检验，也是对广义相对论最有效和最激动人心的检验。目前引力波存在的唯一证据是由中子双星辐射阻尼效应对其的间接证明。当今世界已开展了大量的关于引力波探测的理论和实验工作。本文就是考察了引力波的若干电磁效应，提出了一类新的探测方案并讨论了其可能性，同时扩展了相关的另一类探测方案，使其更加接近实验。 由于引力波的微弱性，产生足够强的引力波需要大质量的剧烈运动，但这在宇宙中是广泛存在的。另外，宇宙早期大爆炸留下的遗迹引力波也是一个很好的观测源。许多天体或天文事件（中子双星，黑洞碰撞等）都能辐射引力波，现今大多数的理论和实验研究都围绕这类天体进行。而在这类天体中不少是被强磁场所包围，在这种情形下，天体辐射的引力波与它周围磁场的相互作用就有可能为引力波探测提供另一种可能的途径，从而与现在流行的地面或空间的激光干涉引力波探测（LIGO，LISA等）形成很好的互补性。本文考察了由于引力波与天体磁场的相互作用而导致的由中子双星等天体辐射的准球面引力波向电磁波的转化。通过求解Einstein-Maxwell方程，并在考...
