e·clips·ing binary

n.
A binary star whose components periodically cross the line of sight from Earth, thereby causing alternating eclipses of one another.

eclipsing binary

or

eclipsing variable

n
(Astronomy) a binary star whose orbital plane lies in or near the line of sight so that one component is regularly eclipsed by its companion. See also variable star

e·clips·ing binary

(ĭ-klĭp′sĭng)
A variable binary star whose components pass in front of each other, thereby causing a regular eclipse of one of the stars and changes in brightness.

The pulsar PSR B1957+20 and the brown dwarf are dancing a cosmic dervish in an eclipsing binary system 6,500 light-years away.
A lot may have been brainwashed into believing the oversimplified statement of 'the Devil you know is better than an Angel you are hoping for.' But that is a mere emotional eclipsing binary designed to make simpletons remain in their comfort zones while dying of the fear of the unknown as combined with the treatment of real issues as a figment of our fantasy.
According to the university, the research team will continue watching this eclipsing binary to measure what could be their crash course into one another.

Most commonly, the light dips are caused by a chance alignment with an "eclipsing binary"--a pair of stars that orbit each other, with one occasionally blocking the light from the other.
By analysing data on the star's varying brightness, using observations from other observatories, the astronomers confirmed the object to be an eclipsing binary system where the smaller component passes in front and behind the larger one as it orbits.
These systems have been publicised in 'Eclipsing Binary News' which continues to be a regular feature of VSS Circulars.
Among the topics are the origin and evolution of helium-rich hot subdwarfs, the high-resolution spectropolarimetric observations of hot subdwarfs, the discovery of a stripped red-giant core in a bright eclipsing binary star, statistical tests for changes inpulsation mode properties, and EO Ceti as an example of a pulsating hot subdwarf with a main-sequence companion.
Krzemenski (1974) declared that the X-ray star Cen X-3 is a component of an eclipsing binary system consists of the star Cen X-3 and a giant optical star of the spectral type B0, with optical magnitude 13.4 mag at a distance of 10 kpc.
The star system is unusual, because it is what the scientists have called a "yellow supergiant eclipsing binary"--it contains two very bright, massive yellow stars that are very closely orbiting each other.
A further seventeen papers address eclipse-related issues of extra-solar physics, including solar and stellar eclipse mapping, line profiles during eclipse of binary stars, classification of eclipsing binaries, photometric and spectroscopic studies of the eclipsing binary, the light curve variation of the Be Star EM Cep, and determination of physical parameters of cataclysmic variables from analysis of their light curves.
