弱孤立层的迈斯纳效应

The Meissner effect for weakly isolated horizons

Norman Gürlebeck, Martin Scholtz

摘要:

黑洞是描述恒星演化终态的重要天体物理对象,是观测的重要对象。理论预测高自旋克尔黑洞会驱逐磁场。然而,克尔黑洞是纯真空的解决方案,其中不包括吸积盘,另外以前的调查主要限于弱磁场。我们第一次在完整的广义相对论中证明了一般的快速旋转的黑洞,包括那些被吸积盘变形的黑洞,仍然会排出甚至很强的磁场。类似于超导体的类似性质,这被称为迈斯纳效应。

英文摘要:

Black holes are important astrophysical objects describing an end state of stellar evolution, which are observed frequently. There are theoretical predictions that Kerr black holes with high spins expel magnetic fields. However, Kerr black holes are pure vacuum solutions, which do not include accretion disks, and additionally previous investigations are mainly limited to weak magnetic fields. We prove for the first time in full general relativity that generic rapidly spinning black holes including those deformed by accretion disks still expel even strong magnetic fields. Analogously to a similar property of superconductors, this is called Meissner effect.
