Boson stars and their relatives in semiclassical gravity
Miguel Alcubierre, Juan Barranco, Argelia Bernal +5
We construct boson star configurations in quantum field theory using the semiclassical gravity approximation. Restricting our attention to the static case, we show that the semicla…
Self-interacting scalar field distributions around Schwarzschild black holes
Alejandro Aguilar-Nieto, Víctor Jaramillo, Juan Barranco +3
Long-lived configurations of massive scalar fields around black holes may form if the coupling between the mass of the scalar field and the mass of the black hole is very small. In…
Determination of the angular momentum of the Kerr black hole from equatorial geodesic motion
Laura O. Villegas, Eduardo Ramirez-Codiz, Víctor Jaramillo +4
We present a method to determine the angular momentum of a black hole, based on observations of the trajectories of the bodies in the Kerr space-time. We use the Hamilton equations…
Head-on collisions of -boson stars
Víctor Jaramillo, Nicolas Sanchis-Gual, Juan Barranco +5
Fully non-linear numerical evolutions of the Einstein-(multi)--Klein-Gordon equations are performed to study head-on collisions of -boson stars. Despite being spherically sym…
On the role of magnetic fields into the dynamics and gravitational wave emission of binary neutron stars
Mariana Lira, Juan Carlos Degollado, Claudia Moreno +1
Modelling as a dipole the magnetic interaction of a binary system of neutron stars, we are able to include the magnetic effects in the Newtonian and in the inspiral dynamics of the…
