KELT-2Ab orbits a star that is slightly bigger than the sun, within a binary system called HD 42176.

Our sun does not orbit another star, but roughly half of the stars in our Milky Way galaxy do, as part of a binary system.

Astronomers using the United Kingdom Infrared Telescope (UKIRT) in Hawaii discovered the four star pairs, each of which is a binary system in which two stars circle each other in less than four hours.

Thus it is that a neutron star in a binary star system gets to spend its retirement years as a millisecond radio pulsar.
Now, an international team of astronomers has trained the Fermi space-based gamma ray telescope on V407 Cygni, a "binary" system comprising a white dwarf star and a red giant companion, 9, 000 light-years away.
This follows the discovery last year by Maciej Konacki, of the California Institute of Technology, of a gaseous giant orbiting a star that is itself orbited by a binary-star system.
"When you have stars in a binary or triple system, and one of them burns all its hydrogen and becomes a red giant, if it's close enough it can start to dump some of its material onto that other star, " he explained to BBC News.
Even stars that are born far away from a giant are still likely to be part of a binary or triple star system.
The black holes are separated by an estimated distance of less than a third of a light-year - cheek-to-cheek by black hole standards and significantly closer than the postulated binary system spotted by the Chandra X-ray Observatory in 2003.
In November Ovshinsky dropped another doozy: He told an audience in Japan that he has made possible a cognitive computer, one that can mimic the human brain by busting through the limitations of conventional computing's binary system.
