论文摘要
我们将重力电磁方法用于爱因斯坦方程在弱场和慢动作近似中的溶液,以研究一般相对性对银河系动力学的影响。特别是,我们专注于引力磁场的一类解决方案,并表明,与预期的相反,它们可能会引入牛顿速度曲线的不可忽略的校正。这些是引力场的同质溶液(HS),即具有消失的物质电流的溶液。我们展示了有关银河动力学的最新结果如何连接到这类解决方案。
We use the gravitoelectromagnetic approach to the solutions of Einstein's equations in the weak-field and slow-motion approximation to investigate the impact of General Relativity on galactic dynamics. In particular, we focus on a class of the solutions for the gravitomagnetic field, and show that, contrary to what is expected, they may introduce non negligible corrections to the Newtonian velocity profile. These are the homogeneous solutions (HS) for the gravitomagnetic field, i.e. solutions with vanishing matter currents. We show how recent results about galactic dynamics are connected to this class of solutions.
