Tau2 Arietis (τ2 Ari, τ2 Arietis) is the Bayer designation for a binary star〔 in the northern constellation on Aries. The combined apparent visual magnitude of this system is +5.09,〔 which is bright enough to be seen with the naked eye. With an annual parallax shift of 10.27 mas,〔 it is located at a distance of approximately from Earth, give or take a 20 light-year margin of error. At this distance the brightness of the star is diminished by 0.18 in magnitude because of extinction from interstellar gas and dust.〔 The primary component is an evolved giant star with a stellar classification of K3 III.〔 It has expanded to 19 times the radius of the Sun, from which it is radiating 120 times the Sun's luminosity.〔 This energy is being emitted into outer space from the outer atmosphere at an effective temperature of 4,406 K,〔 giving it the cool orange glow of a K-type star. At an angular separation of 0.53 arcseconds is a magnitude 8.50 companion.〔 ==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「Tau2 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.
