Motion of spinning test bodies in Kerr spacetime
Eva Hackmann, Claus Lämmerzahl, Yuri N. Obukhov +2
We investigate the motion of spinning test bodies in General Relativity. By means of a multipolar approximation method for extended test bodies we derive the equations of motion, a…
Compact (A)dS Boson Stars and Shells
Betti Hartmann, Burkhard Kleihaus, Jutta Kunz +1
We present compact Q-balls in an (Anti-)de Sitter background in D dimensions, obtained with a V-shaped potential of the scalar field. Beyond critical values of the cosmological con…
Geodesic motion in the space-time of a non-compact boson star
Valeria Diemer, Keno Eilers, Betti Hartmann +2
We study the geodesic motion of test particles in the space-time of non-compact boson stars. These objects are made of a self-interacting scalar field and -- depending on the scala…
Compact Boson Stars
Betti Hartmann, Burkhard Kleihaus, Jutta Kunz +1
We consider compact boson stars that arise for a V-shaped scalar field potential. They represent a one parameter family of solutions of the scaled Einstein-signum-Gordon equations.…
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…
