An eclipsing binary star is a binary star system in which the orbital plane of the two stars lies so nearly in the line of sight of the observer that the components undergo mutual eclipses. [20] In the case where the binary is also a spectroscopic binary and the parallax of the system is known, the binary is quite valuable for stellar analysis.
LL Aquarii is an eclipsing binary star system in the equatorial constellation of Aquarius, abbreviated LL Aqr.At peak brightness it has a combined apparent visual magnitude of 9.23, [1] which is too dim to be visible to the naked eye.
KIC 9832227 is a contact binary star system in the constellation Cygnus, located about 2,060 light-years away. It is also identified as an eclipsing binary with an orbital period of almost 11 hours.

Algol variables or Algol-type binaries are a class of eclipsing binary stars that are similar to the prototype member of this class, β Persei (Beta Persei, Algol). An Algol binary is a system where both stars are near-spherical such that the timing of the start and end of the eclipses is well-defined.
The following is a list of variable stars that are well-known, ... Eclipsing binary Algol type (EA/GS) R Aur: Auriga 6 m.7 13 m.9 7.2: 458 d Mira variable (M)
RR Caeli is an eclipsing binary star system, located 69 light-years from Earth in the constellation Caelum.It is made up of a red dwarf star and a white dwarf, which complete an orbit around each other every seven hours.
Alpha Coronae Borealis is a binary system, its stars orbiting each other in an eccentric orbit every 17.36 days. Because the plane of this orbit is inclined at an angle of 88.2° to the line of sight to the Earth, [8] the pair form a detached eclipsing binary system similar to Algol (β Per). The periodic eclipses result in a magnitude ...
