Dynamical Instability of Gaseous Sphere in the Reissner-Nordstrom Limit
M. Sharif, Saadia Mumtaz
In this paper, we study the dynamical instability of gaseous sphere under radial oscillations approaching the Reissner-Nordström limit. For this purpose, we derive linearized pertu…
Stability Analysis of Axial Reflection Symmetric Spacetime
M. Sharif, M. Zaeem Ul Haq Bhatti
In this paper, we explore instability regions of non-static axial reflection symmetric spacetime with anisotropic source in the interior. We impose linear perturbation on the Einst…
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…
Instability Analysis of Cylindrical Stellar Object in Brans-Dicke Gravity
M. Sharif, Rubab Manzoor
This paper investigates instability ranges of a cylindrically symmetric collapsing stellar object in Brans-Dicke theory of gravity. For this purpose, we use perturbation approach i…
