This binary star system consists of a red giant (Mira, designated Mira A) undergoing mass loss and a high-temperature white dwarf companion (Mira B) that is accreting mass from the primary. Such an arrangement of stars is known as a symbiotic system and this is the closest such symbiotic pair to the Sun.
Mira B, also known as VZ Ceti, is the companion star to the variable star Mira, separated by around 100 AU. Suspected as early as 1918, it was visually confirmed in 1923 by Robert Grant Aitken , and has been observed more or less continually since then, most recently by the Chandra X-Ray Observatory .
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.
The newly-discovered binary star system, which is home to two stars gravitationally bound to one another, was found in a dense stellar cluster orbiting Sagittarius A*, which has an estimated mass ...
R Aquarii is a symbiotic star believed to contain a white dwarf and a Mira-type variable in a binary system. The orbital period is approximately 44 years. [ 6 ] The main Mira-type star is a red giant , and varies in brightness by a factor of several hundred and with a period of slightly more than a year; this variability was discovered by Karl ...

X Ophiuchi is a binary star system in the equatorial constellation of Ophiuchus, abbreviated X Oph.It is a Mira variable that ranges in brightness from an apparent visual magnitude of 5.9 down to 9.2 with a period of 328.85 days. [3]
LL Pegasi (AFGL 3068) is a Mira variable star surrounded by a pinwheel-shaped nebula, IRAS 23166+1655, thought to be a preplanetary nebula. It is a binary system that includes an extreme carbon star. The pair is hidden by the dust cloud ejected from the carbon star and is only visible in infrared light. [8]
