Some new class of Chaplygin Wormholes
F. Rahaman, M. Kalam, K. A. Rahman
Some new class of Chaplygin wormholes are investigated in the framework of a Chaplygin gas with equation of state , . Since empty spacetime () do…
Particle Motion Around Tachyon Monopole
M. Kalam, F. Rahaman, S. Mondal
Recently, Li and Liu have studied global monoole of tachyon in a four dimensional static space-time. We analyze the motion of massless and massive particles around tachyon monopole…
Gravitational lensing by stable C-field wormhole
F. Rahaman, M. Kalam, S. Chakraborty
It has been recently shown that Hoyle-Narlikar's C-field theory admits wormhole geometry. We derive the deflection angle of light rays caused by C-field wormhole in the strong fiel…
Construction of 3D wormhole supported by phantom energy
F. Rahaman, M. Kalam, B. C. Bhui +1
In this article, we have found a series solution of 3D Einstein equations describing a wormhole for an inhomogeneous distribution of phantom energy. Here, we assume equation of sta…
A Theoretical Construction of Thin Shell Wormhole from Tidal Charged Black hole
F. Rahaman, M. Kalam, K A Rahman +1
Recently, Dadhich et al [ Phys.Lett.B 487, 1 (2000)] have discovered a black hole solution localized on a three brane in five dimensional gravity in the Randall-Sundrum scenario. I…
Vacuum less global monopole in Brans-Dicke theory
F. Rahaman, M. Kalam, R. Mukherjee +2
In the present work, the gravitational field of a vacuum less global monopole has been investigated in Brans-Dicke theory under weak field assumption of the field equations. It has…
