Photometric study of three ultrashort-period contact binaries
L. Liu, S. -B., E. Fernandez Lajus +3
We carried out high-precision photometric observations of three eclipsing ultrashortperiod contact binaries (USPCBs). Theoretical models were fitted to the light-curves by means of…
Solar energetic particles and radio burst emission
Rositsa Miteva, Susan W. Samwel, Vratislav Krupar
We present a statistical study on the observed solar radio burst emission associated with the origin of in situ detected solar energetic particles. Several proton event catalogs in…
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,…
The photometric study of the non-relaxed cluster "Mayer 3"
A. L. Tadross, R. Bendary, P. Hasan
The astrophysical parameters of the open star cluster Mayer 3 have been estimated using the Newtonian focus (f/4.84) of the 1.88 m Telescope of Kottamia Observatory in Egypt. The V…
Topological Origin of Holographic Principle: Application to wormholes
Nasr Ahmed, Hisham Rafat
In this paper, we suggest a mathematical representation to the holographic principle through the theory topological retracts. We found that the topological retraction is the mathem…
Computational Method for a Fractional Model of the Helium Burning Network
Mohamed I. Nouh
Stellar cores may be considered as a nuclear reactor that play important role in injecting new synthesized elements in the interstellar medium Helium burning is an important stage…
Distant clusters of galaxies in the 2XMM/SDSS footprint: follow-up observations with the LBT
Andreas Rabitz, Georg Lamer, Axel Schwope +1
Context: Galaxy clusters at high redshift are important to test cosmological models and models for the growth of structure. They are difficult to find in wide-angle optical surveys…
OISTER Optical and Near-Infrared Monitoring Observations of a Peculiar Radio-Loud Active Galactic Nucleus SDSS J110006.07+442144.3
Tomoki Morokuma, Masaomi Tanaka, Yasuyuki T. Tanaka +80
We present monitoring campaign observations at optical and near-infrared (NIR) wavelengths for a radio-loud active galactic nucleus (AGN) at z=0.840, SDSS~J110006.07+442144.3 (here…
Solar energetic particle catalogs: assumptions, uncertainties and validity of reports
R. Miteva, S. W. Samwel, M. V. Costa-Duarte
The aim of this work is to summarize the main underlying assumptions, simplifications and uncertainties while studying solar energetic particles (SEPs). In general, numerous defini…
About influence of differential rotation in convection zone of gaseous or fluid giant Planet (Uranus) onto the parameters of orbits of satellites
Sergey V. Ershkov, Dmytro Leshchenko, Elbaz I. Abouelmagd
Tidal interactions between Planet and its satellites are known to be the main phenomena, which are determining the orbital evolution of the satellites. We suggest in the current re…
Approximate solution to the fractional Lane-Emden type equations
M. I. Nouh, Emad A-B. Abdel-Salam
In this paper, approximate solutions for a class of fractional Lane - Emden type equations based on the series expansion method are presented. Various examples are introduced and d…
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…
Light Curve Modelling and Evolutionary Status of the Short Period Binary 1SWASP J092328.76+435044
M. M. Elkhateeb, M. I. Nouh, R. Michel +2
Light curve modeling for the newly discovered system 1SWASP J092328.76+435044 was carried out by using a new BVR complete light curves. A spotted model was applied to treat the asy…
