拓扑星与黑洞

Topological Stars and Black Holes

Ibrahima Bah, Pierre Heidmann

摘要:

我们研究了在Kaluza-Klein约化下类似于四维磁性黑洞的五维爱因斯坦-麦克斯韦理论中的光滑泡时空。我们称它们为拓扑星,因为它们具有由磁通量支持的拓扑环。与卡鲁扎-克莱因圆的大小相比,它们可以是宏观上的大,并且可以描述天体物理学黑洞微观几何的定性性质。我们还描述了没有曲率奇异性的五维黑弦,其内部是一个带泡的二维Milne空间。

英文摘要:

We study smooth bubble spacetimes in five-dimensional Einstein-Maxwell theory that resemble four-dimensional magnetic black holes upon Kaluza-Klein reduction. We denote them as Topological Stars since they have topological cycles supported by magnetic flux. They can be macroscopically large compared to the size of the Kaluza-Klein circle and could describe qualitative properties of microstate geometries for astrophysical black holes. We also describe five-dimensional black strings without curvature singularity, the interior caps as a two-dimensional Milne space with a bubble.
