Circular orbits and particle collisions in the space-time of boson stars and their frozen states
Maria Chivers, Betti Hartmann, Katherine Horton +1
In this paper, we discuss the dynamics of test particles in the space-time of spherically symmetric, charged boson stars and their frozen states. These latter objects consist of a…

Circular orbits and particle collisions close to charged black holes surrounded by scalar clouds
Maria Chivers, Betti Hartmann, Katherine Horton +1
We study the motion of massive (un)charged test particles in space-times of electric and dyonic black holes which carry scalar hair. We determine the stable and unstable circular o…
