Cosmographic analysis of a closed bouncing universe with the varying cosmological constant in gravity
Vinod Kumar Bhardwaj, Anirudh Pradhan, Nasr Ahmed +1
Modeling of matter bounce in gravity has been presented with no violation of the null energy condition. Only a closed universe with negative pressure is allowed in good ag…
Stability Analysis of Relativistic Polytropes
A. S. Saad, M. I. Nouh, A. A. Shaker +1
A main question in astrophysics and cosmology has been the severe stability of the astrophysical objects, whether a particular equilibrium configuration is stable. In this article,…
Approximate Analytical Solutions to the Relativistic Isothermal Gas Spheres
A. S. Saad, M. I. Nouh, A. A. Shaker +1
In this paper, we introduce a novel analytical solution to Tolman-Oppenheimer-Volkoff (TOV) equation, which is ultimately a hydrostatic equilibrium equation derived from the genera…
