Stability Analysis Of Fractional Relativistic Polytropes
Mohamed S. Aboueisha, A. S. Saad, Mohamed I. Nouh +3
In astrophysics, the gravitational stability of a self-gravitating polytropic fluid sphere is an intriguing subject, especially when trying to comprehend the genesis and developmen…
Analysis of the Fractional Relativistic Polytropic Gas Sphere
Mohamed S. Aboueisha, Mohamed I. Nouh, Emad A-B. Abdel-Salam. Tarek M. Kamel +2
Many stellar configurations, including white dwarfs, neutron stars, black holes, supermassive stars, and star clusters, rely on relativistic effects. The Tolman-Oppenheimer-Volkoff…
Investigating the hyperbolic and hybrid scalar field cosmologies with varying cosmological constant in gravity
Nasr Ahmed, Tarek M. Kamel
This paper investigated two scalar field cosmological models in gravity with cosmic transit and varying cosmological constant .The cosmological constant tends to hav…
Note on Dark Energy and Cosmic Transit in a scale-invariance cosmology
Nasr Ahmed, Tarek M. Kamel
In general, the laws of physics are not invariant under a change of scale. To find out whether the 'scale-invariance hypothesis' corresponds to nature or not, a careful examination…
