翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク NGC 2516 ： ウィキペディア英語版 NGC 2516 NGC 2516 is an open star cluster in the southern sky in the constellation Carina discovered by Abbe Lacaille in 1751-1752. It is most commonly referred to as NGC 2516 but is also known as the Sprinter.〔"''Imaging the Southern Sky : An Amateur Astronomer’s Guide''" Chadwick, S., Cooper, I., pg.viii, Pub. Springer (2012)〕 ==Description== This bright cluster itself is easily visible with the naked eye as a hazy patch, but is resolvable into stars using binoculars. It contains two 5th magnitude red giant stars and three main visual double stars: HJ 4027, HJ 4031 and I 29. A small telescope would be required to split the double stars, which are all pairs of 8-9 magnitude and 1-10 arcseconds separation.〔Burnham (1978), Vol I p.458〕 NGC 2516 and the recently discovered nearby star cluster Mamajek 2 in Ophiuchus have similar age and metallicity. Recently, kinematic evidence was presented by E. Jilinksi and coauthors that suggests that these two stellar groups may have formed in the same star-forming complex some 135 million years ago. 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「NGC 2516」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.
