Schwarzschild black holes can wear scalar wigs
Juan Barranco, Argelia Bernal, Juan Carlos Degollado +5
We study the evolution of a massive scalar field surrounding a Schwarzschild black hole and find configurations that can survive for arbitrarily long times, provided the black hole…
Induced scalarization in boson stars and scalar gravitational radiation
Milton Ruiz, Juan Carlos Degollado, Miguel Alcubierre +2
The dynamical evolution of boson stars in scalar-tensor theories of gravity is considered in the physical (Jordan) frame. We focus on the study of spontaneous and induced scalariza…
Stability study of a model for the Klein-Gordon equation in Kerr spacetime
Horst Reinhard Beyer, Miguel Alcubierre, Miguel Megevand +1
The current early stage in the investigation of the stability of the Kerr metric is characterized by the study of appropriate model problems. Particularly interesting is the proble…
