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…
First Orbital Solution and Evolutionary State for the Newly Discovered Eclipsing Binaries USNO-B1.0 1091-0130715 and GSC-03449-0680
M. M. Elkhateeb, M. I. Nouh, R. H. Nelson
First photometric study for the newly discovered systems USNO-B1.0 1091-0130715 and GSC-03449-0680 were applied by means of recent windows interface version of the Wilson and Devin…
Computational Algorithm for Orbit and Mass Determination of Visual Binaries
Mohamed Sharaf, Mohamed Nouh, Abdel Naby Saad +2
In this paper we introduce an algorithm for determining the orbital elements and individual masses of visual binaries. The algorithm uses an optimal point, which minimizes a specif…
Spectroscopic Analysis of the Double Lined Eclipsing Binary αVir
M. I. Nouh, S. M. Saad, I. Zaid +2
αVir is a well known double-lined spectroscopic binary with a B-type for both components. In the present paper we have analyzed a total of 90 spectra obtained through 1992-2000. Sp…
Indirect evidence for short period magnetic cycles in W UMa stars
T. Borkovits, M. M. Elkhateeb, Sz. Csizmadia +4
Complex period variations of five W UMa type binaries (AB And, OO Aql, DK Cyg, V566 Oph, U Peg) were investigated by analyzing their O--C diagrams, and several common features were…
