标题： Gravoelectromagnetic approach to the gravitational Faraday rotation in stationary spacetimes

摘要： 使用静态时空的1+3分解，在引力电磁学的框架下，我们表明，接近黑洞的光线的偏振平面会发生旋转。我们证明这种旋转具有与通常法拉第效应相同的积分形式，即它与沿传播路径的引力磁场分量的积分成正比。我们将这个积分公式应用于计算克尔空间和NUT空间引起的法拉第旋转，使用真空爱因斯坦方程的准麦克斯韦形式。 显示英文摘要

摘要： Using the 1+3 formulation of stationary spacetimes we show, in the context of gravoelectromagnetism, that the plane of the polarization of light rays passing close to a black hole undergoes a rotation. We show that this rotation has the same integral form as the usual Faraday effect, i.e. it is proportional to the integral of the component of the gravomagnetic field along the propagation path. We apply this integral formula to calculate the Faraday rotation induced by the Kerr and NUT spaces using the quasi-Maxwell form of the vacuum Einstein equations.
