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…
the impact of the AGN and the torus properties on the evolution of spiral galaxies
M. A. Abdulrahman, K. A. K. Gadallah, A. Ahmed +1
For spiral galaxies, the active galactic nucleus (AGN) and some physical parameters that concern the host galaxy such as spiral arm radius and density can play an important role in…
Estimating the coronal and chromospheric magnetic fields of solar active regions as observed with the Nobeyama Radioheliograph Compared with the Extrapolated Linear Force-Free Field
A. Mouner, Abdelrazek M. K. Shaltout, M. M. Beheary +2
Adopting the thermal free-free emission mechanism, the coronal and chromospheric magnetic fields are derived from the polarization and spectral observations with the Nobeyama Radio…
Stellar parameters of Be stars observed with X-shooter
A. Shokry, Th. Rivinius, A. Mehner +10
Aims. The X-shooter archive of several thousand telluric star spectra was skimmed for Be and Be-shell stars to derive the stellar fundamental parameters and statistical properties,…
Orbital solution and evolutionary state for the eclipsing binary 1SWASP J080150.03+471433.8
M. S. Darwish, M. M. Elkhateeb, M. I. Nouh +5
We present an orbital solution study for the newly discovered system 1SWASP J080150.03+471433.8 by means of new CCD observations in VRI bands. Our observations were carried out on…
