Kompletní popis

This work studies orbital circularization of binary§stars past the Main Sequence using two new samples of§eclipsing binary stars found in the Magellanic Clouds§by the MACHO Project, as well as samples introduced§by the OGLE-II project and finds strong evidence of§orbit circularization past the Main Sequence phase of§stellar evolution, by the almost complete absence of§systems with eccentric orbits in the Red Giant part§of the Color Magnitude Diagram whereas the Main§Sequence exhibits systems with a broad range of§eccentricities.§This absence allows to robustly conclude that binary§stars§circularize their orbits either on crossing the§Hertzsprung Gap or on ascending the Red Giant Branch§when they undergo a sudden and dramatic increase in§their dimensions resulting in strong tidal forces§that disrupt the orbit.§The work then quantifies the effects of tidal§interaction and distortions via a a thorough study of§the Specific Dissipation Function Q, which is§generally not well known for binary stars and finds§evidence of a low degree of tidal dissipation.
