Gravitational instability in higher dimensions

We explore a classical instability of spacetimes of dimension D > 4. Firstly, we consider static solutions: generalised black holes and brane world metrics. The dangerous mode is a tensor mode on an Einstein base manifold of dimension D−2. A criterion for instability is found for the generalised Schwarzschild, AdSSchwarzschild and topological black hole spacetimes in terms of the Lichnerowicz s...

Gravitational coupling constant in higher dimensions

Assuming the equivalence of FRW-cosmological models and their Newtonian counterparts, we propose using the Gauss law in arbitrary dimension a general relation between the Newtonian gravitational constant G and the gravitational coupling constant κ.

Gravitational Field of A Radiating Star in Higher Dimensions

We obtain fields of a relativistic radiating star of non-static mass in the framework of higher dimensional spacetime. Assuming energy-momentum tensor in Higher dimensions analogous to that considered by Vaidya in 4 dimensions we obtain solution of a radiating spherically symmetric star. The solution obtained here is new in higher dimensions which however reduces to that obtained by Vaidya in 4...

Nonlinear Instability in Gravitational

The dynamics of gaseous stars can be described by the EulerPoisson system. Inspired by Rein’s stability result for γ > 4 3 , we prove the nonlinear instability of steady states for the adiabatic exponent γ = 6 5 in spherically symmetric and isentropic motion.
