Sowmya Puttaraju,Tony Brian D’souzaew absolute dimensions of the system were calculated using the results of the light-curve analysis. Period variation of the system was also investigated. Several new times of minima have been secured for this problematic system. An apsidal motion with a period of 80.7 years was confirmed and a third

The quadratic variation can be explained in terms of mass exchange/loss mechanism in the system, while the cyclic variation could be attributed to the light

Scham — ein menschliches Gefühlof 12 years were analyzed with a Wilson-Devinney-based solution code. Setting off from a set of parameters derived from spectroscopic investigations a consistent photometric solution was achieved. In accordance with the spectroscopic findings the eccentricity was determined as . = 0.128 and the apsi

Among the systems of our observing list are CK Boo, V502 Oph and V836 Cyg that show long-term secular variations in their orbital periods. We use classical O-C diagram analysis technique as a tool to reveal the character of the period variations of these binary

Such an inclination can induce ‘Kozai cycles’ (.), in which the eccentricity of the inner orbit cycles by a large amount while its period and therefore semimajor axis remains roughly constant. During those periastra when the eccentric
