Born-Infeld boson stars
Víctor Jaramillo, Daniel Martínez-Carbajal, Juan Carlos Degollado +1
We study the Einstein-Klein-Gordon system coupled to the Born-Infeld electrodynamics. We explore the solution space of a static spherically symmetric, complex scalar field minimall…
Confinement of exotic matter. I. Static solutions
Víctor Jaramillo, Erik Jiménez-Vázquez, Darío Núñez
We present the -boson star: A novel configuration of a boson star with an exotic matter nucleus; the exotic matter being described by a real massive scalar field with sel…
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…
Introduction to the ADM formalism
Alejandro Corichi, Dario Núñez
The authors present concepts and mathematical developments which give rise to the Hamiltonian formulation of Einstein's general relativity, first introduced by Arnowitt, Deser, and…
Magnetostatic boson stars
Víctor Jaramillo, Darío Núñez
We solve the Einstein-Maxwell-Klein-Gordon system of equations and derive a compact, static axially symmetric magnetized object which is electrically neutral and made of two comple…
Generalized harmonic spatial coordinates and hyperbolic shift conditions
Miguel Alcubierre, Alejandro Corichi, José A. González +3
We propose a generalization of the condition for harmonic spatial coordinates analogous to the generalization of the harmonic time slices introduced by Bona et al., and closely rel…
