Eclipsing binaries observed with the WIRE satellite. II, β Aurigae and non-linear limb darkening in light curves [PDF]

, 2007
Aims. We present the most precise light curve ever obtained of a detached eclipsing binary star and use it investigate the inclusion of non-linear limb darkening laws in light curve models of eclipsing binaries.

EL CVn-type binaries - discovery of 17 helium white dwarf precursors in bright eclipsing binary star systems [PDF]

, 2014
The star 1SWASP J024743.37−251549.2 was recently discovered to be a binary star in which an A-type dwarf star eclipses the remnant of a disrupted red giant star (WASP 0247−25 B).

Absolute dimensions of eclipsing binaries. XXVI, Setting a new standard : masses, radii, and abundances for the F-type systems AD Bootis, VZ Hydrae, and WZ Ophiuchi [PDF]

, 2008
Context. Accurate mass, radius, and abundance determinations from binaries provide important information on stellar evolution, fundamental to central fields in modern astrophysics and cosmology. Aims.

Turbulence in the Atmospheres of Eclipsing Binary Stars [PDF]

International Astronomical Union Colloquium, 1980
Abstract:A review of the orbits and dimensions of the ζ Aurigae systems is given, based on photometric and spectrographic observations. The Ca II K-line has been studied intensively to determine the extent and uneven structure of the chromospheres of these stars; the multiple structure of this line observed at several eclipses confirms the presence of ...

HD 46407: The First Eclipsing-Binary Barium Star [PDF]

Symposium - International Astronomical Union, 1992
A long-term, high-accuracy, differential uvby monitoring of a sample of 19 barium stars revealed that HD 46407, a well known barium star with an orbital period of 458 d, is an eclipsing binary. The eclipse (of the companion by the barium star) was most clearly seen in November 1988, when a dip of 0.02 mag (in y) having a FWHM of about 10 d was recorded

Line of sight errors in eclipsing binary stars

, 2022
This paper will illustrate the line of sight errors in eclipsing binary stars. Due to this error, the eclipsing binary stars will not actually along be along the line of sight when the observer sees them as eclipsing. This is due to the longer time taken

Accurate fundamental parameters of eclipsing binary stars [PDF]

, 2004
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 WW Aurigae, which is

Eclipsing Binary Stars from Space [PDF]

Proceedings of the International Astronomical Union, 2006
AbstractWe 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.

The Surface Brightness-color Relations Based on Eclipsing Binary Stars: Toward Precision Better than 1% in Angular Diameter Predictions [PDF]

, 2017
In this study we investigate the calibration of surface brightness–color (SBC) relations based solely on eclipsing binary stars. We selected a sample of 35 detached eclipsing binaries with trigonometric parallaxes from Gaia DR1 or Hipparcos whose ...
