Negative Komar masses in regular stationary spacetimes |
Abstract _ |
A highly accurate multi-domain spectral method is used to study axially symmetric and stationary spacetimes containing a black hole or disk 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 disk can become negative. A continuous transition from such disks to such black holes can be found. |
