This is an astrometric binary system.〔 The primary has a stellar classification of F2 III,〔 suggesting that it is a giant star. Despite being an evolved star with four〔 times the radius of the Sun, it is spinning rapidly with a projected rotational velocity of 139.6 km/s.〔 This is causing a pronounced equatorial bulge, with the radius of the star along the equator being 24% greater than the radius at the poles.〔 The star shines at 32〔 times the luminosity of the Sun, with this energy being radiated from its outer atmosphere at an effective temperature of 6,761 K.〔 This heat gives it the yellow-white hued glow of an F-type star.〔 ==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「14 Arietis」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.
