Perfect Fluid Dark Matter
F. Rahaman, K. K. Nandi, A. Bhadra +2
Taking the flat rotation curve as input and treating the matter content in the galactic halo region as perfect fluid, we obtain space time metric at the galactic halo region in the…
Revisiting the classical electron model in general relativity
Farook Rahaman, Mubasher Jamil, Kaushik Chakraborty
Electron is modeled as a spherically symmetric charged perfect fluid distribution of matter. The existing model is extended assuming a matter source that is characterized by quadra…
Classical electron model with non static conformal symmetry
I. Radinschi, F. Rahaman, M. Kalam +1
Lorentz proposed a classical model of electron in which electron was assumed to have only 'electromagnetic mass'. We modeled electron as charged anisotropic perfect fluid sphere ad…
Chaplygin electron gas model
I. Radinschi, F. Rahaman, M. Kalam +1
We provide a new electromagnetic mass model admitting Chaplygin gas equation of state. We investigate three specializations, the first characterized by a vanishing effective pressu…
On the role of pressure anisotropy for relativistic stars admitting conformal motion
Farook Rahaman, Mubasher Jamil, Mehedi Kalam +2
We investigate the spacetime of anisotropic stars admitting conformal motion. The Einstein field equations are solved using different ansatz of the surface tension. In this investi…
