Dynamical Analysis of Charged Anisotropic Spherical Star in f(R) Gravity

H. Rizwana Kausar, Ifra Noureen, M. Umair Shahzad

We consider a modified gravity theory, $f (R) = R + α R^{n} - \frac{μ ^{4}}{R ^{m}}$ , in the metric formulation and analyze the contribution of electromagnetic field on the range of dynamical inst…

Newtonian and Post Newtonian Expansionfree Fluid Evolution in f(R) Gravity

M. Sharif, H. Rizwana Kausar

We consider a collapsing sphere and discuss its evolution under the vanishing expansion scalar in the framework of $f (R)$ gravity. The fluid is assumed to be locally anisotropic wh…

Dust Static Spherically Symmetric Solution in $f (R)$ Gravity

Muhammad Sharif, Hafiza Rizwana Kausar

In this paper, we take dust matter and investigate static spherically symmetric solution of the field equations in metric f(R) gravity. The solution is found with constant Ricci sc…
