Black holes in the Brans-Dicke-Maxwell theory

The black hole solutions in the higher dimensional BransDicke-Maxwell theory are investigated. We find that the presence of the nontrivial scalar field depends on the spacetime dimensions (D). WhenD = 4, the solution corresponds to the Reissner-Nordström black hole with a constant scalar field. In higher dimensions (D > 4), one finds the charged black hole solutions with the nontrivial scalar f...

Black hole area in Brans-Dicke theory.

We have shown that the dynamics of the scalar field φ(x) = “G−1(x)” in BransDicke theories of gravity makes the surface area of the black hole horizon oscillatory during its dynamical evolution. It explicitly explains why the area theorem does not hold in Brans-Dicke theory. However, we show that there exists a certain non-decreasing quantity defined on the event horizon which is proportional t...

Evolution of primordial black holes in Jordan-Brans-Dicke cosmology

We consider the evolution of primordial black holes in a generalized Jordan-BransDicke cosmological model where both the Brans-Dicke scalar field and its coupling to gravity are dynamical functions determined from the evolution equations. The evaporation rate for the black holes is different from the case in standard cosmology. We show that the accretion of radiation can proceed effectively in ...

Evolution of Black Holes in Brans-Dicke Cosmology

We consider a modified “Swiss cheese” model in the Brans-Dicke theory, and discuss the evolution of black holes in the expanding universe. We define the black hole radius by the Misner-Sharp mass and find the time evolution for dust and vacuum universes.

Cylindrically Symmetric-Static Brans-Dicke-Maxwell Solutions

We present static cylindrically symmetric electrovac solutions in the framework of the Brans-Dicke theory and show that our solution yields some of the well-known solutions for special values of the parameters of the resulting metric functions.
