It is one of the largest and most luminous stars known in the Milky Way. It appears garnet red and is given the spectral class of M2 Ia. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified.〔 ==History== The deep red color of Mu Cephei was noted by William Herschel, who described it as "a very fine deep garnet colour, such as the periodical star ο Ceti".〔 It is thus commonly known as Herschel's "Garnet Star".〔 Mu Cephei was called ''Garnet sidus'' by Giuseppe Piazzi in his catalogue.〔 An alternative name, ''Erakis'', used in Antonín Bečvář's star catalogue, is probably due to confusion with Mu Draconis, which was previously called ' (:arˈraːqis) in Arabic.〔 In 1848, English astronomer John Russell Hind discovered that Mu Cephei was variable. This variability was quickly confirmed by German astronomer Friedrich Wilhelm Argelander. Almost continual records of the star's variability have been maintained since 1881.〔 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「Mu Cephei」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.
