Statistical Study of Visual Binaries
H. I. Abdel-Rahman, M. I. Nouh, W. H. Elsanhoury
In this paper, some statistical distributions of wide pairs included in Double Star Catalogue are investigated. Frequency distributions and testing hypothesis are derived for some…
A Photometric Study of Four Recently Discovered Contact Binaries: 1SWASP J064501.21+342154.9, 1SWASP J155822.10-025604.8, 1SWASP J212808.86+151622.0 and UCAC4 436-062932
G. Djurašević, A. Essam, O. Latković +4
We present new, high-quality multicolor observations of four recently discovered contact binaries: 1SWASP J064501.21+342154.9, 1SWASP J155822.10-025604.8, 1SWASP J212808.86+151622.…
The first photometric analysis of the W-subtype contact binary UCAC4 436-062932 with O'Connell effect
X. Zhou, S. -B. Qian, A. Essam +2
Two sets of light curves in bands for a newly discovered binary system UCAC4 436-062932 are obtained and analyzed using the Wilson-Devinney (W-D) code. The two sets…
The 3XMM/SDSS Stripe 82 Galaxy Cluster Survey: Cluster catalogue and discovery of two merging cluster candidates
Ali Takey, Florence Durret, Eman A. Mahmoud +1
We present a galaxy cluster survey based on XMM-Newton observations that are located in Stripe 82 of the Sloan Digital Sky Survey (SDSS). The survey covers an area of 11.25 deg…
Spectral Clustering for Optical Confirmation and Redshift Estimation of X-ray Selected Galaxy Cluster Candidates in the SDSS Stripe 82
Eman Mahmoud, Ali Takey, Amin Shoukry
We develop a galaxy cluster finding algorithm based on spectral clustering technique to identify optical counterparts and estimate optical redshifts for X-ray selected cluster cand…
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…
2MASS photometry and kinematical studies of open cluster NGC 188
W. H. Elsanhoury, A. A. Haroon, N. V. Chupina +4
In this paper, we present our results for the photometric and kinematical studies of old open cluster NGC 188. We determined various astrophysical parameters like limited radius, c…
Analytical Solution to the Fractional Polytropic Gas Spheres
Mohamed I. Nouh, Emad A-B. Abdel-Salam
Lane-Emden equation could be used to model stellar interiors, star clusters and many configurations in astrophysics. Unfortunately, there is an exact solution only for the polytrop…
Light Curve Analysis of GSC 2750-0054 and GSC 03208-02644
M. M. Elkhateeb, M. I. Nouh
We present the first photometric analysis for the newly discovered eclipsing binary systems of Algole-type GSC 2750-0054 and GSC 03208-02644. Our analysis was carried out by means…
