旋转黑洞附近磁场的标架拖曳效应

Frame-dragging effects on magnetic fields near a rotating black hole

V. Karas, O. Kopacek, D. Kunneriath

摘要:

本文讨论了广义相对论框架拖曳作用于旋转(克尔)黑洞附近磁场的作用。在能层附近,磁结构受到强烈的影响,磁零点可以发展。我们考虑对齐的磁场以及相对于旋转轴倾斜的领域,这两种情况下表现出深刻的不同方式。此外,我们还构造了等值的局部电场强度和磁场强度的表面,这还没有在一个助推旋转黑洞的充分普遍性进行讨论。

英文摘要:

We discuss the role of general relativity frame dragging acting on magnetic field lines near a rotating (Kerr) black hole. Near ergosphere the magnetic structure becomes strongly influenced and magnetic null points can develop. We consider aligned magnetic fields as well as fields inclined with respect to the rotation axis, and the two cases are shown to behave in profoundly different ways. Further, we construct surfaces of equal values of local electric and magnetic intensities, which have not yet been discussed in the full generality of a boosted rotating black hole.
