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...

A Quintessence Problem in Self-interacting Brans-Dicke Theory

The Standard Cosmological Model (SCM) can only describe decelerated universe models and so cannot reproduce the results coming from the recent type Ia supernovae observations upto about z ∼ 1 [1] which favour an accelerated current universe. But as the SCM can give a satisfactory explanation to other observational properties of the present universe (e.g., primordial nucleosynthesis, extragalact...

Self - Similar Collapse in Brans - Dicke Theory

We use the technique of conformal transformations to generate self-similar collapse in Brans-Dicke theory. We analyze the solutions concerning the critical behavior found recently by Choptuik. The critical exponent associated to the formation of black hole for near critical evolution is obtained. The role of the coupling parameter is discussed.

Black Hole Criticality in the Brans-Dicke Model.

Studies of black hole formation from the gravitational collapse of a massless scalar field have revealed interesting nonlinear phenomena at the threshold of black hole formation [1,2]. These studies have shown that Einstein’s field equations possess solutions which occur precisely at the black hole threshold and which are universal with respect to the initial conditions of the evolution. More s...
