(2+1) dimensional cosmological models in f(R; T) gravity with (R; T)
Safiqul Islam, Praveen Kumar, G. S. Khadekar +1
We intend to study a new class of cosmological models in modified theories of gravity, hence define the cosmological constant as a function of the trace of the stress…
Magnetic Field of a Compact Spherical Star under f(R,T) Gravity
Safiqul Islam, Shantanu Basu
We present the interior solutions of distributions of magnetised fluid inside a sphere in gravity. The magnetised sphere is embedded in an exterior Reissner-Nordström metr…
Charged wormholes supported by 2-fluid immiscible matter particles
Safiqul Islam, Md Arif Shaikh, Tapas Kumar Das +2
We provide a 2-fluid immiscible matter source that supplies fuel to construct wormhole spacetime. The exact wormhole solutions are found in the model having, besides real matter or…
A Reissner-Nordström black hole in the Friedman-Robertson-Walker universe
Safiqul Islam, Priti Mishra, Somi Aktar +1
A charged, non-rotating, spherically symmetric black hole which has cosmological constant (Reissner-Nordström+ or RN+), active gravitational mass and electric charge…
The higher dimensional gravastars
Farook Rahaman, Subenoy Chakraborty, Saibal Ray +2
A new model of gravastar is obtained in -dimensional Einstein gravity. This class of solutions includes the gravastar as an alternative to D-dimensional versions of the Schwarzs…
The (2+1)-dimensional charged gravastars
Farook Rahaman, A. A. Usmani, Saibal Ray +1
This is a continuation and generalization of our earlier work on {\it gravastar} in (2+1) anti-de Sitter space-time to 2+1 dimensional solution of charged gravastar. Morphologicall…
Wormholes supported by two non-interacting fluids
Farook Rahaman, Saibal Ray, Safiqul Islam
We provide a new matter source that supplies fuel to construct wormhole spacetime. The exact wormhole solutions are found in the model having, besides real matter, an anisotropic d…
