Apsidal Motion Determination of the Eclipsing Binary Star V459 Cassiopeiae
Photometric and spectroscopic observations and analysis of the eccentric eclipsing binary V459 Cassiopeiae (e = 0.0244) were performed by Lacy et al. (2004). Observations of minimum light show the presence of apsidal motion. In order to find the observed rate of apsidal motion, I followed the procedure described by Guinan & Maloney (1985). A new observed rate of apsidal motion of 15◦.2/100 yr w...
متن کاملRetrograde Spin-Orbit coupling Effects on the apsidal motion of Eclipsing Binary Star Systems: the case of V541Cygni
It is usually known that the line of apsides of eclipsing binary star systems precesses due to general relativistic effects and classical (Newtonian) tidal and rotational deformations of the stars, whose rotation axes are assumed normal to the orbital plane. For almost all binaries, the expected theoretical and observed apsidal motion rates are in agreement. However, some systems –V541 Cygni, V...
متن کاملThe apsidal motion in binary stars. B.V.Vasiliev
The apsidal motion in binary stars. Abstract It is usually accepted to consider an apsidal motion in binary stars as a direct confirmation that a substance inside stars is not uniformly distributed. It is shown in this paper that the apsidal motion in binary systems observation data is in a good agreement with an existence of uniform plasma cores inside stars if they consist of hydrogen-deuteri...
متن کاملComputationally efficient and robust frequency-domain GSC
In this paper, we propose a novel adaptive beamforming algorithm with low signal distortion capability and high computational efficiency. The proposed algorithm incorporates the crosstalk-resistant adaptive noise canceller (CTRANC) in place of the usual adaptive interference canceller (AIC). Doing so, a better signal leakage estimate is provided at the adaptive interference canceller input but ...
