Nonlinear Stability of Rotating Hairy Black Holes
Juan A. Carretero, Philippe Grandclément, Carlos Palenzuela +1
Rotating hairy black holes (RHBHs) are axisymmetric equilibrium solutions of the Einstein--Klein--Gordon equations, consisting of a spinning black hole surrounded by a toroidal dis…

Solar system tests and neutron stars in gravity revisited
Hodek M. GarcÃa, Marcelo Salgado
By implementing a full non-linear treatment of gravity in static and spherically symmetric spacetimes, we analyze two scenarios. The first one within the context of the sola…

Dynamical transition to spontaneous scalarization in neutron stars: The massive scalar field scenario
Juan Carlos Degollado, Néstor Ortiz, Marcelo Salgado
We analyze numerically the dynamical transition to spontaneous scalarization in neutron stars in the framework of a scalar-tensor theory of gravity where the scalar field is free b…
