Eclipsing binaries in the Magellanic Clouds [PDF]
We present results of a search for eclipsing binaries in the Magellanic Cloud fields covering central parts of these galaxies. The data were collected during the second phase of the Optical Gravitational Lensing Experiment survey (OGLE-II) in 1997-2000.

Spectral Classification of Eclipsing Binaries [PDF]
Approximately 375 classification spectra of 130 Southern Hemisphere eclipsing binary stars were obtained between 1978 and 1982 at Mt. John University Observatory, New Zealand using the 0.6 meter reflector, and at Cerro Tololo Inter-American Observatory, Chile using the 0.4, 0.6, 0.9, and 1.0 meter telescopes.

Investigation of the Eclipsing Binary AN Tauri [PDF]
AN Tau has been classified as the β Lyrae-type variable. The only visual light curve was published 55 years ago. The star was observed photoelectrically during a few last years at Mt. Suhora and Skalnaté Pleso Observatories. The complete light curve was obtained in B and V band passes.

Planets transiting non-eclipsing binaries [PDF]
The majority of binary stars do not eclipse. Current searches for transiting circumbinary planets concentrate on eclipsing binaries, and are therefore restricted to a small fraction of potential hosts. We investigate the concept of finding planets transiting non-eclipsing binaries, whose geometry would require mutually inclined planes.

Physics of Eclipsing Binaries. IV. The Impact of Interstellar Extinction on the Light Curves of Eclipsing Binaries [PDF]
Abstract Traditionally, the effects of interstellar extinction on binary star light curves have been treated as a uniform reduction in the observed brightness of the system that is independent of the orbital phase. However, unless the orbital plane of the system coincides with the plane of the sky, or if the two stars are completely ...

An eccentric eclipsing binary: CG Aur [PDF]
In this study, we present CG Aur's photometric observations obtained in the observing seasons 2011 and 2012, the first available multi-colour light curves. Their shape indicates that the system is an Algol binary. The light curve analyses reveal that CG Aur is a detached binary system with an effective temperature difference between the components ...

Parameterization of long-period eclipsing binaries [PDF]
Abstract One of the important sources for independent determination of stellar masses is eclipsing binaries with components on the main sequence, and with observable spectral lines of both components. The parameters of such stars are used to construct the mass–luminosity relation for stars of high and intermediate masses. Among them, the

Eclipsing Binaries in Multiple Star Systems [PDF]
Although the majority of the known eclipsing binaries are in systems which consist of only the two eclipsing components, a significant number of them do occur as components of triple star systems or higher order multiple star systems. In this context this term is restricted to those systems whose components are in closed orbits.

Analysis of the massive eclipsing binary V1441Aql [PDF]
We present new spectroscopic observations of the early type, double-lined eclipsing binary V1441\,Aql. The radial velocities and the available photometric data obtained by $ASAS$ is analysed for deriving the parameters of the components. The components of V1441\,Aql are shown to be a B3\,IV primary with a mass M$_p$=8.02$\pm$0.51 M$_{\odot}$ and radius

Eclipsing binary statistics – Theory and observation [PDF]
The expected distributions of eclipse-depth versus period for eclipsing binaries of different luminosities are derived from large-scale population synthesis experiments. Using the rapid Hurley et al. BSE binary evolution code, we have evolved several hundred million binaries, starting from various simple input distributions of masses and orbit-sizes ...
