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…
Wormhole and C-field: Revisited
F. Rahaman, M. Sarker, M. Kalam
Recently, Rahaman et al [ Nuovo.Cim 119B, 1115(2004)] have shown that the static spherically symmetric solutions in presence of C-field give rise to wormhole geometry. We highlight…
Do Solar system tests permit higher dimensional general relativity?
F. Rahaman, Saibal Ray, M. Kalam +1
We perform a survey whether higher dimensional Schwarzschild space-time is compatible with some of the solar system phenomena. As a test we examine five well known solar system eff…
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…
