It has the traditional name Adhafera (Aldhafera, Adhafara), from the Arabic الضفيرة ''al-ðafīrah'' "the braid/curl", a reference to its position in the lion's mane. It forms the second star (after Gamma Leonis) in the blade of "The Sickle", which is an asterism formed from the head of Leo.〔 == Properties == Adhafera is a giant star with a stellar classification of F0 III. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified.〔 Its apparent magnitude is +3.44, making it relatively faint for a star that is visible to the naked eye. Nevertheless, it shines with 85 times the luminosity of the Sun.〔 Adhafera has about three times the Sun's mass〔 and six times the radius of the Sun.〔 Parallax measurements from the Hipparcos satellite yield an estimated distance to Adhafera of 〔 from Earth. Adhafera forms a double star with an optical companion that has an apparent magnitude of 5.90. Known as 35 Leo, this star is separated from Adhafera by 325.9 arcseconds along a position angle of 340°.〔〔 The two stars do not form a binary star system as 35 Leo is only 100 light years from Earth. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zeta Leonis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
