2 1 Se p 20 07 A universal constraint between charge and rotation rate for degenerate black holes surrounded by matter
نویسنده
چکیده
We consider stationary, axially and equatorially symmetric systems consisting of a central rotating and charged degenerate black hole and surrounding physically realistic matter. We show that a + Q = M always holds, where a = J/M is the black hole’s intrinsic angular momentum per unit mass, Q its electric charge and M the well known black hole mass parameter introduced by Christodoulou and Ruffini.

2 4 Ja n 20 08 A universal constraint between charge and rotation rate for degenerate black holes surrounded by matter
We consider stationary, axially and equatorially symmetric systems consisting of a central rotating and charged degenerate black hole and surrounding matter. We show that a + Q = M always holds provided that a continuous sequence of spacetimes can be identified, leading from the Kerr-Newman solution in electrovacuum to the solution in question. The quantity a = J/M is the black hole’s intrinsic...

The most massive black holes, lurking at the centers of large galaxies, must have formed less than a billion years after the big bang, as they are visible today in the form of bright quasars at redshift larger than six. Their early appearance is mysterious, because the radiation pressure, generated by infalling ionized matter, inhibits the rapid growth of these black holes from stellar-mass bla...
متن کاملThermodynamics of Near-Extreme Black Holes
The thermodynamics of nearly-extreme charged black holes depends upon the number of ground states at fixed large charge and upon the distribution of excited energy states. Here three possibilities are examined: (1) Ground state highly degenerate (as suggested by the large semiclassical Hawking entropy of an extreme ReissnerNordstrom black hole), excited states not. (2) All energy levels highly ...
