正则定常时空中的负Komar质量

Negative Komar Masses in Regular Stationary Spacetimes

Marcus Ansorg, David Petroff

摘要:

一个高精度的多域谱方法被用来研究轴对称和静态时空包含一个黑洞或磁盘的尘埃包围的一环的物质。它表明,物质环可以影响中心对象的属性急剧。特别是,由于环的坐标系拖曳,黑洞或圆盘的所谓科马尔质量可以变为负值。我们可以发现从这样的圆盘到这样的黑洞的连续过渡。

英文摘要:

A highly accurate multi-domain spectral method is used to study axially symmetric and stationary spacetimes containing a black hole or disc of dust surrounded by a ring of matter. It is shown that the matter ring can affect the properties of the central object drastically. In particular, by virtue of the ring's frame dragging, the so-called Komar mass of the black hole or disc can become negative. A continuous transition from such discs to such black holes can be found.
