Rotating Boson Stars and Q-Balls II: Negative Parity and Ergoregions
Burkhard Kleihaus, Jutta Kunz, Meike List +1
We construct axially symmetric, rotating boson stars with positive and negative parity. Their flat space limits represent spinning Q-balls. -balls and boson stars exist only in…
Rotating Black Holes in Higher Dimensions
Burkhard Kleihaus, Jutta Kunz, Francisco Navarro-Lerida
The properties of higher-dimensional black holes can differ significantly from those of black holes in four dimensions, since neither the uniqueness theorem, nor the staticity theo…
Interior of Nonuniform Black Strings
Burkhard Kleihaus, Jutta Kunz
We consider nonuniform black strings inside their event horizon. We present numerical evidence, that the singularity touches the horizon as the horizon topology changing transition…
Nonabelian solutions in a Melvin magnetic universe
Burkhard Kleihaus, Jutta Kunz, Eugen Radu
We show the existence of D=4 nonabelian solutions approaching asymptotically a dilatonic Melvin spacetime background. An exact solution generalizing the Chamseddine-Volkov soliton…
Gravitating Dyons with Large Electric Charge
Rustam Ibadov, Burkhard Kleihaus, Jutta Kunz +1
We consider non-Abelian dyons in Einstein-Yang-Mills-Higgs theory. The dyons are spherically symmetric with unit magnetic charge. For large values of the electric charge the dyons…
Orbits in the Field of a Gravitating Magnetic Monopole
Valeria Kagramanova, Jutta Kunz, Claus Laemmerzahl
Orbits of test particles and light rays are an important tool to study the properties of space-time metrics. Here we systematically study the properties of the gravitational field…
