Charged Gravastars in Modified Gravity
Z. Yousaf, Kazuharu Bamba, M. Z. Bhatti +1
In this paper, we investigate the effects of electromagnetic field on the isotropic spherical gravastar models in metric gravity. For this purpose, we have explored singul…
Influence of Electric Charge and Modified Gravity on Density Irregularities
M. Zaeem Ul Haq Bhatti, Z. Yousaf
This work aims to identify some inhomogeneity factors for plane symmetric topology with anisotropic and dissipative fluid under the effects of both electromagnetic field as well as…
The Influence of Modification of Gravity on the Dynamics of Radiating Spherical Fluids
Z. Yousaf, Kazuharu Bamba, M. Zaeem ul Haq Bhatti
We explore the evolutionary behaviors of compact objects in a modified gravitational theory with the help of structure scalars. Particularly, we consider the spherical geometry cou…
Instability of Meridional Axial System in f(R) Gravity
M. Sharif, Z. Yousaf
We analyze dynamical instability of non-static reflection axial stellar structure by taking into account generalized Euler's equation in metric gravity. Such an equation is…
Energy Density Inhomogeneities with Polynomial Cosmology
M. Sharif, Z. Yousaf
In this paper, we study the effects of polynomial model on the stability of homogeneous energy density in self-gravitating spherical stellar object. For this purpose, we con…
Stability of a Class of Non-Static Axial Self-Gravitating Systems in Gravity
M. Sharif, Z. Yousaf
In this paper, we analyze stability regions of a non-static restricted class of axially symmetric spacetime with anisotropic matter distribution. We consider model an…
Expansion-free Cylindrically Symmetric Models
M. Sharif, Z. Yousaf
This paper investigates cylindrically symmetric distribution of an-isotropic fluid under the expansion-free condition, which requires the existence of vacuum cavity within the flui…
Shearfree Spherically Symmetric Fluid Models
M. Sharif, Z. Yousaf
We try to find some exact analytical models of spherically symmetric spacetime of collapsing fluid under shearfree condition. We consider two types of solutions: one is to impose a…
