Analysis of light curves and apsidal motion of neglected southern eclipsing binary V399 Pup

Bulut, İ.; Çiçek, C.; Bulut, A.

In this study, the Hipparcos and ASAS light curves of the eclipsing binary V399 Pup have been analyzed using the Wilson-Devinney program. The light curve analyses have found that V399 Pup is a detached binary system with eccentric orbit. The apsidal motion parameters of the system have been obtained from the O-C curve analyses. The system has been…

NR Peg: A new highly active semi-detached binary

Erdem, A.; Oblak, E.; Kurpińska-Winiarska, M. +1 more

This paper presents the first analysis of spectroscopic and photometric observations of the eclipsing binary star NR Peg. ELODIE Hα observations indicate that the secondary component is a chromospherically active star; however, the spectral line profiles (especially of neutral metals) of NR Peg are very wide and have a complex structure with asymm…
