An eccentric eclipsing binary: CG Aur [PDF]
New Astronomy, 2013 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 ...

Eclipsing Binaries in the Magellanic Clouds [PDF]
Highlights of Astronomy, 2004 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.

Eclipsing binary stars in the era of massive surveys First results and future prospects
EPJ Web of Conferences, 2017 Our thinking about eclipsing binary stars has undergone a tremendous change in the last decade. Eclipsing binary stars are one of nature’s best laboratories for determining the fundamental physical properties of stars and thus for testing the predictions

The Mass and Angular Momentum Relation of Eclipsing Binaries [PDF]
Journal of Astronomy and Space Sciences, 1998 With a total 3780 eclipsing binary system in the Catalogue of Approximate Photometric and Absolute Elements of Eclipsing Variable Stars by Svechnikov & Kuznetsova (1990), the empirical relations between the systemic mass and orbital angular momentum have

Parameterization of long-period eclipsing binaries [PDF]
Open Astronomy, 2022 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

Odessa Astronomical Publications, 2013 We discuss methods for modeling eclipsing binary stars. There are few realizations of the Wilson- Devinney (1971) code and its improvements, e.g. “Binary Makef’, “Phoebe”. A parameter search using the Monte- Carlo method was realized by Zola et al. (2010)

Eclipsing Binaries in Multiple Star Systems [PDF]
Symposium - International Astronomical Union, 1992 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.

A Search for Exoplanets in Short-Period Binary Star Systems [PDF]
Journal of Astronomy and Space Sciences, 2012 This paper reports the progress of a search for exoplanets with S-type orbits in short-period binary star systems. The selected targets have stellar orbital periods of just a few days. These systems are eclipsing binaries so that exoplanet transits, if

Close-In Substellar Companions and the Formation of sdB-Type Close Binary Stars
Acta Polytechnica CTU Proceedings, 2015 The sdB-type close binaries are believed to have experienced a common-envelope phase and may evolve into cataclysmic binaries (CVs). About 10% of all known sdB binaries are eclipsing binaries consisting of very hot subdwarf primaries and low-mass ...
