Determined from Observations of the Eclipsing Binary OGLEGC 17
We use masses, radii, and luminosities of the detached eclipsing binary OGLEGC17 derived from photometric and spectroscopic observations to calculate the age and distance of the globular cluster ω Cen. Age versus turnoff mass and age versus luminos-ity relations from Girardi et al. (2000) yield two independent estimates of the age, 9.1 < t < 16.7 Gyr and 12.9 < t < 18.5 Gyr. The distance and di...
متن کاملEclipsing Binary Pulsars
The first eclipsing binary pulsar, PSR B1957+20, was discovered in 1987. Since then, 13 other eclipsing low-mass binary pulsars have been found; 12 of these are in globular clusters. In this paper we list the known eclipsing binary pulsars and their properties, with special attention to the eclipsing systems in 47 Tuc. We find that there are two fundamentally different groups of eclipsing binar...
متن کاملSPITZER 24 m TIME SERIES OBSERVATIONS OF THE ECLIPSING M DWARF BINARY GU BOÖTIS
We present a set of Spitzer 24 mMIPS time series observations of the M dwarf eclipsing binary star GU Boötis. Our data cover three secondary eclipses of the system: two consecutive events and an additional eclipse 6 weeks later. The study’s main purpose is the long-wavelength (and thus limb-darkening-independent) characterization of GUBoo’s light curve, allowing for independent verification of ...
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 کاملEclipsing 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...
