The apsidal motion test of stellar structure in relativistic systems
We have compared observational data of apsidal motion rates for relativistic eclipsing binaries with theoretical predictions based on stellar theoretical models. Ten double-lined eclipsing binaries with high quality light curves and radial velocities were selected. The analysis of the data available indicate that the predictions by the General Relativity and the new stellar models are able to e...
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 کاملResonant dynamic tides and apsidal motion in close binaries
The resonance of a dynamic tide with a free oscillation mode in a component of a close binary system of stars is treated by means of a two-time variable expansion procedure. The treatment is developed with respect to a frame of reference corotating with the star. Both the free oscillation mode and the dynamic tide are considered as linear, isentropic perturbations of a spherically symmetric sta...
متن کاملBehavior of Apsidal Orientations in Planetary Systems
A widely considered characteristic of extra-solar planetary systems has been a seeming tendency for major axes of adjacent orbits to librate in stable configurations. Based on a new catalog of extra-solar planets (Butler et al. 2006) and our numerical integrations, we find that such small amplitude oscillations are actually not common, but in fact quite rare; most pairs of planets’ major axes a...
متن کاملSome notes on the relativistic apsidal motion of DI Herculis
DI Her is a double-lined eclipsing binary presenting a very slow apsidal motion for which the relativistic contribution is of the order of the newtonian one. The observed apsidal motion is around 4 times that predicted by stellar evolutionary models and by General Relativity. This trend is known for non-relativistic systems although in a minor scale. The magnitude of such a disagreement led som...
