摘要

我们首次证明，旋转虫洞在吸积磁化物质的过程中能够发射出波因通量。为此，我们分析了描述克尔型虫洞的达穆尔-索洛杜金公设，并计算了假设虫洞麦哲伦所含磁场的特定几何形状的电磁通量。我们发现，对于高度旋转的虫洞来说，类似于布兰福德和兹纳杰克的机制是可能的，而且发射的电磁通量与克尔黑洞的电磁通量是同阶的。

Outgoing electromagnetic flux from rotating wormholes

We show for the first time that rotating wormholes are capable of emitting a Poynting flux in the process of accreting magnetized matter. To this end, we analyze the Damour–Solodukhin metric describing a Kerr-type wormhole and calculate the electromagnetic flux assuming a specific geometry for the magnetic field contained by the wormhole ergosphere. We find that for highly rotating wormholes a mechanism similar to that of Blandford and Znajek is possible, and the emitted electromagnetic flux is of the same order as for a Kerr black hole.
