• Eclipsing Binaries.
• When one star passes directly in front of the other, as viewed from Earth, we seen an eclipsing binary.
• An eclipsing binary occurs when the orbital plane of the binary system is exactly perpendicular to the plane of the sky.

• AAVSO Eclipsing Binary Workshop.
• Here is the material from the workshop on eclipsing binaries held at the Spring 2001 meeting in Madison: .

• ECLIPSING BINARY STARS OBSERVING PROJECT.
• Eclipsing binary stars show regular light variations caused by one star passing directly in front of its companion as seen from the Earth. Eclipsing binaries are extremely useful systems, which enable astronomers to measure almost every interesting property of the stars in them (mass, radius, luminosity). ... Some 4,000 eclipsing systems are known, but less than 10% of them have had their orbits determined and only a much smaller number have orbits good enough to determine all the properties of interest. ...

• The two star trackers, with 22-degree field of views and pointing 180 degrees apart, will be very useful instruments for obtaining light curves of known eclipsing binaries and discovering new ones.
• A number of papers have dealt with the MONS contributions to the study of eclipsing binaries. ... Particular aspects of eclipsing binaries are studied within the context of MONS (eccentric systems, systems with pulsating components, second order light curve effects). In contrast, this web page is intended to be a short general summary of the wide range of astrophysical problems that can be studied with eclipsing binaries. ...
• What are eclipsing binaries useful for?.
• The most interesting fact about eclipsing binaries is that all kinds of stars are found as members of binaries: from normal main sequence stars, variable stars, evolved giants and supergiants, to collapsed objects. ... The following table summarizes the most remarkable properties of each major class of eclipsing binaries and their importance to Astrophysics:.
• Detached Eclipsing Binaries.
• Eclipsing Binaries in Eccentric Orbits.
• Eclipsing Binaries with Variable Components.

• Welcome to the Eclipsing Binaries Homepage.

• Observations of Eclipsing Binary Stars Binary stars are quite common. ... These binary stars are so far away from us that they look like single stars in photographs, but their brightness varies in a particular way due to the eclipses - these are known as eclipsing binary stars. ... Eclipsing binary stars are a rich source of information about the physical properties (mass, size, luminosities, internal structure, etc. ... In fact, the American astronomer Henry Norris Russell called the study of eclipsing binaries the "Royal Road to the stars. ... The investigation of an eclipsing binary star usually proceeds through a number of stages. ... Most eclipsing binaries have been discovered in surveys covering large sections of the sky looking specifically for stars whose brightness varies (variable stars). ... As a byproduct, they found a large number (611) of eclipsing binary stars (Alcock et al. ... The figure below shows a light curve of one of these eclipsing binaries in the LMC. ... Thus the study of eclipsing binary stars severely limits the models that describe our understanding of stars. ...
