Andromeda is one of the 48 constellations listed by the 2nd-century Greco-Roman astronomer Ptolemy, and one of the 88 modern constellations.Located in the northern celestial hemisphere, it is named for Andromeda, daughter of Cassiopeia, in the Greek myth, who was chained to a rock to be eaten by the sea monster Cetus.
XZ Andromedae (also known as XZ And) is a binary star in the constellation Andromeda. Its maximum apparent visual magnitude is 9.91, but drops down to 12.45 every 1.357 days. Its variability matches the behaviour of Algol variable stars. [3]
Alpheratz / æ l ˈ f ɪər æ t s /, [13] [14] or Alpha Andromedae (α Andromedae, abbreviated Alpha And or α And), is a binary star 97 light-years from Earth and is the brightest star in the constellation of Andromeda when Mirach (β Andromedae) undergoes its periodical dimming.
RX Andromedae is a cataclysmic variable system, where a white dwarf with a mass of 0.8 M ☉ and an M2 main sequence star [9] are rotating around their center of mass. The main sequence star is overfilling its Roche lobe, so the white dwarf is stripping away matter from the companion star and accreting it through an accretion disk.
Zeta Andromedae (Zeta And, ζ Andromedae, ζ And) is a star system in the constellation Andromeda. It is approximately 189 light-years from Earth. Zeta Andromedae is the star's Bayer designation. It also has the Flamsteed designation 34 Andromedae and multiple other designations in stellar catalogues.
Lambda Andromedae, Latinized from λ Andromedae, is the Bayer designation for a binary star system in the northern constellation of Andromeda. At an estimated distance of approximately 84.6 light-years (25.9 parsecs) from Earth, [1] it has an apparent visual magnitude of +3.8. [5] This is bright enough to be seen with the naked eye.
Xi Andromedae (ξ Andromedae, abbreviated Xi And, ξ And), officially named Adhil / ə ˈ d ɪ l /, [7] [8] is a solitary [3] star in the northern constellation of Andromeda. It has an apparent magnitude of +4.9. [2] Based on parallax measurements obtained during the Gaia mission, it lies at a distance of roughly 223 light-years (68 parsecs ...
AB Andromedae (AB And) is a binary star in the constellation Andromeda. Paul Guthnick and Richard Prager discovered that the star is an eclipsing binary in 1927. [11] [12] Its maximum apparent visual magnitude is 9.49 but shows a variation in brightness down to a magnitude of 10.46 in a periodic cycle of roughly 8 hours.
