Statistical Evidence for Contributions of Flares and Coronal Mass Ejections to Major Solar Energetic Particle Events
G. Trottet, S. Samwel, K. -L. Klein +2
Solar energetic particle (SEP) events are related to flares and coronal mass ejections (CMEs). This work is a new investigation of statistical relationships between SEP peak intens…
Detailed ROSAT X-ray Analysis of the AM Her Cataclysmic Variable VV Pup
M. I. Nouh, E. El Kholy
VV Pup is typical system of AM Her stars, where the main accreting pole rotates in and out of view during the orbital cycle. In the present paper we present ROSAT data analysis for…
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…
Modern Comprehensive study of the W UMa System TY Boo
M. M. Elkhateeb, M. I. Nouh, A. S. Saad
New CCD three colors light curves of TY Boo were carried out in five nights from February to May 2006 in BVR bandpass using a 50-cm F/8.4 Ritchey Chretien telescope (Ba50) of the B…
A New Analytical Solution to the Relativistic Polytropic Fluid Spheres
Mohamed Nouh, Abdelnaby Saad
This paper introduces an accelerated power series solution for Tolman-Oppenheimer-Volkoff (TOV) equation, which represents the relativistic polytropic fluid spheres. We constructed…
An Extensive Photometric Investigation of the W UMa System DK Cyg
M. M. Elkhateeb, M. I. Nouh, E. Elkholy +1
DK Cyg (P = 0.4707) is a W Ursae Majoris type eclipsing binary system that undergoes complete eclipses. All the published photoelectric data have been collected and utilized to re-…
White Dwarf Stars as Polytropic Gas Spheres
M. I. Nouh, A. S. Saad, M. M. Elkhateeb +1
Due to the highly degeneracy of electrons in white dwarf stars, we expect that the relativistic effects play very important role in these stars. In the present article, we study th…
New CCD photometric observation of the W-UMa eclipsing binary system 1swasp j160156.04+202821.6
A. Essam, Nasser M. A
New BVRI light curves of the eclipsing binary system 1SWASP J160156.04+202821.6 have been obtained with the 1.88-m telescope of Kottamia Astronomical Observatory (KAO), Egypt on Ju…
Photometric Investigation of the Total-Eclipsing Contact Binary V12 in the Intermediate-age Open Cluster NGC 7789
S. -B. Qian, A. Essam, J. -J. Wang +3
NGC 7789 is an intermediate-age open cluster with an age that is similar to the mean age of contact binary stars. V12 is a bright UMa-type binary star with an orbital period of 0.3…
