Star
A star is an astronomical object comprising a luminous spheroid of plasma held together by its gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye, all within the Milky Way galaxy. A star's life begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Its total mass is the main factor determining its evolution and eventual fate. A star shines for most of its active life due t ...

Xi Andromedae
Xi Andromedae (ξ Andromedae, abbreviated Xi And, ξ And), officially named Adhil , is a solitary star in the northern constellation of Andromeda. It has an apparent magnitude of +4.9. Based on parallax measurements obtained during the Gaia mission, it lies at a distance of roughly from the Sun. Nomenclature ''ξ Andromedae'' ( Latinised to ''Xi Andromedae'') is the star's Bayer designation. It also bears the Flamsteed designation ''46 Andromedae''. Johann Bayer labeled this star "ξ" in his '' Uranometria''. The star appeared in John Flamsteed's ''Atlas Coelestis'', but was unlabeled. It was later designated as ''46 And'' by Jérôme Lalande. The label "ξ" was used in ''Atlas Coelestis'', apparently erroneously, for what Bayer had labeled "A" (Bayer's ''A Andromedae'' has the Flamsteed designation ''49 Andromedae''). It bore the traditional name ''Adhil'', which is derived from the Arabic الذيل ''að-ðayl'' "the train" (lit. "the tail"). In 2016, the Intern ...

60 Andromedae
60 Andromedae (abbreviated 60 And) is a star system in the northern constellation of Andromeda, located to the west-northwest of Gamma Andromedae. ''60 Andromedae'' is the Flamsteed designation though the star also bears the Bayer designation b Andromedae.

Omega Andromedae
Omega Andromedae (ω And, ω Andromedae) is the Bayer designation for a slowly co-rotating binary star system in the northern constellation of Andromeda. Parallax measurements made during the ''Gaia'' mission make this system to be approximately from Earth. Its apparent visual magnitude is +4.83, which makes it bright enough to be seen with the naked eye. The primary component has a stellar classification of F5 IVe. The IV luminosity class indicates that it is probably a subgiant star that is in the process of evolving away from the main sequence as the supply of hydrogen at its core depletes. However, Abt (1985) gives a classification of F3 V, suggesting it is an F-type main-sequence star. The measured angular diameter of the primary star is . At the system's estimated distance this yields a size of about 2.2 times that of the Sun. It is emitting about seven times solar luminosity from its outer atmosphere at an effective temperature of .

Upsilon Andromedae
Upsilon Andromedae (υ Andromedae, abbreviated Upsilon And, υ And) is a binary star located 44 light-years from Earth in the constellation of Andromeda. The system consists of an F-type main-sequence star (designated υ Andromedae A, officially named Titawin in the Amazigh language ) and a smaller red dwarf. , four extrasolar planets (designated Upsilon Andromedae b, c, d and e; the first three named Saffar, Samh and Majriti, respectively) are believed to orbit υ Andromedae A.
