Photon emissivity of the electrosphere of bare strange stars
T. Harko, K. S. Cheng
We consider the spectrum, emissivity and flux of the electromagnetic radiation emitted by the thin electron layer (the electrosphere) at the surface of a bare strange star. In part…
Time delay of photons of different energies in multi-dimensional cosmological models
T. Harko, K. S. Cheng
We consider the general expressions for the time delay of photons of different energies in the framework of multi-dimensional cosmological models. In models with compactified extra…
Anisotropy in Bianchi-type brane cosmologies
T. Harko, M. K. Mak
The behavior near the initial singular state of the anisotropy parameter of the arbitrary type, homogeneous and anisotropic Bianchi models is considered in the framework of the bra…
Vacuum solutions of the gravitational field equations in the brane world model
T. Harko, M. K. Mak
We consider some classes of solutions of the static, spherically symmetric gravitational field equations in the vacuum in the brane world scenario, in which our Universe is a three…
