翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Iota1 Scorpii ： ウィキペディア英語版 Iota1 Scorpii Iota1 Scorpii (ι1 Scorpii) is star in the southern constellation of Scorpius. With an apparent visual magnitude of 3.03,〔 this star can be seen with the naked eye. It is sometimes called by the proper name Apollyon.〔 Parallax measurements place it at a distance of roughly from Earth, with a 9% margin of error.〔 This star has a stellar classification of F2 Ia,〔 with the 'Ia' luminosity class indicating this is an evolved star that has expanded to become a supergiant. It has about 12 times the Sun's mass〔 and is radiating about 35,070 times the Sun's luminosity.〔 The radius is uncertain, with estimates ranging from 125〔 to 400〔 times that of the Sun. The effective temperature of the outer envelope is about 7,000 K,〔 which gives it a yellow-white hue typical of an F-type star.〔 Iota1 Scorpii has a 10th magnitude companion at an angular separation of 37.5 arcseconds, which, at the distance of this star, gives it a projected physical separation of 20,000 Astronomical Units (AU). As the relative separation of the two stars along the line of sight to the Earth is not known, however, this distance represents only a minimum value for their separation.〔 ==References== 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「Iota1 Scorpii」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.
