Located around 420 light-years distant, it shines with a luminosity approximately 154 times that of the Sun and has a surface temperature of 10,695 K. It is a Be star, the presence of hydrogen emission lines in its spectrum indicating it has a circumstellar disk. It is separated by 7 arcseconds from the star HR 4691. The two may be an optical double or a true multiple star system, with a separation of at least 50,000 astronomical units and the stars taking 3.5 million years to orbit each other. HR 4691 is itself double, composed of an ageing yellow-orange giant whose spectral type has been calculated at K0 or G3, and an F-type main sequence star. ==Reference== 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 Corvi」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.
