Particle motion in Horava-Lifshitz black hole space-times
Victor Enolskii, Betti Hartmann, Valeria Kagramanova +3
We study the particle motion in the space-time of a Kehagias-Sfetsos (KS) black hole. This is a static spherically symmetric solution of a Horava-Lifshitz gravity model that reduce…
Hyperelliptic integrals and Hořava-Lifshitz black hole space-times
Victor Enolski, Betti Hartmann, Valeria Kagramanova +3
The description of many dynamical problems like the particle motion in higher dimensional spherically and axially symmetric space-times is reduced to the inversion of hyperelliptic…
Detection of cosmic superstrings by geodesic test particle motion
Betti Hartmann, Claus Lämmerzahl, Parinya Sirimachan
(p,q)-strings are bound states of p F-strings and q D-strings and are predicted to form at the end of brane inflation. As such these cosmic superstrings should be detectable in the…
Geodesic motion in the space-time of a cosmic string
Betti Hartmann, Parinya Sirimachan
We study the geodesic equation in the space-time of an Abelian-Higgs string and discuss the motion of massless and massive test particles. The geodesics can be classified according…
Test particle motion in the space-time of a Kerr black hole pierced by a cosmic string
Eva Hackmann, Betti Hartmann, Claus Laemmerzahl +1
We study the geodesic equation in the space-time of a Kerr black hole pierced by an infinitely thin cosmic string and give the complete set of analytical solutions of this equation…
The complete set of solutions of the geodesic equations in the space-time of a Schwarzschild black hole pierced by a cosmic string
Eva Hackmann, Betti Hartmann, Claus Laemmerzahl +1
We study the geodesic equations in the space-time of a Schwarzschild black hole pierced by an infinitely thin cosmic string and give the complete set of analytical solutions of the…
