e·clips·ing binary

 (ĭ-klĭp′sĭng)
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.

According to the university, the research team will continue watching this eclipsing binary to measure what could be their crash course into one another.
In 2008, his old Optical Craftsmen telescope helped in the discovery of a new eclipsing binary star (V1047 Persei).
Objective: We propose to carry out a project which will produce a decisive step towards improving the accuracy of the Hubble constant as determined from the Cepheid-SN Ia method to 1%, by using 28 extremely rare eclipsing binary systems in the LMC which offer the potential to determine their distances to 1%.
Additional observations of the system made by the Center for Backyard Astrophysics (CBA), a collaboration of amateur and professional astronomers, found that the system is a rare eclipsing binary, where one star passes directly in front of the other, completely blocking it out when viewed from Earth.

While one eclipsing binary getting in the way is possible, two isn't likely.
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.
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.
