Eclipsing Binary Stars from Space
We have begun a programme to obtain high-precision photometry of bright detached eclipsing binary (dEB) stars with the Wide field InfraRed Explorer (wire) satellite (Bruntt & Buzasi 2006). Due to the small aperture of wire only stars brighter than V = 6 can be observed. We are collecting data for about a dozen dEB targets and here we present preliminary results for three of them. We have chosen...
متن کاملAccurate fundamental parameters of eclipsing binary stars
The study of detached eclipsing binaries is one of the most powerful ways to investigate the properties of individual stars and stellar systems. We present preliminary masses, radii and effective temperatures for the eclipsing binary WWAurigae, which is composed of two metallic-lined A-type stars. We also reanalyse the data on HD23642, an A-type eclipsing binary member of the Pleiades open clus...
متن کاملGravitational lensing in eclipsing binary stars
I consider the effect of the gravitational deflection of light upon the light curves of eclipsing binary stars, focussing mainly upon systems containing at least one white dwarf component. In absolute terms the effects are small, however they are strongest at the time of secondary eclipse when the white dwarf transits its companion, and act to reduce the depth of this feature. If not accounted ...
متن کاملAutomated analysis of eclipsing binary lightcurves. I. EBAS — a new Eclipsing Binary Automated Solver with EBOP
We present a new algorithm— Eclipsing Binary Automated Solver (EBAS), to analyse lightcurves of eclipsing binaries. The algorithm is designed to analyse large numbers of lightcurves, and is therefore based on the relatively fast EBOP code. To facilitate the search for the best solution, EBAS uses two parameter transformations. Instead of the radii of the two stellar components, EBAS uses the su...
متن کاملEccentric Orbits of Close Companions to Asymptotic Giant Branch Stars
I propose that the relatively high eccentricity 0.1 ∼< e ∼< 0.4 found in some tidally strongly interacting binary systems, where the mass-losing star is an evolved giant star, e.g., an asymptotic giant branch star, is caused by an enhanced mass loss rate during periastron passages. Tidal interaction by itself will circularize the orbits of these systems in a relatively short time, hence a mecha...
