Trumpler 14 is an open cluster with a diameter of six light-years, located within the inner regions of the Carina Nebula, approximately light-years from Earth. Together with the nearby Trumpler 16, they are the main clusters of the Carina OB1 stellar association, which is the largest association in the Carina Nebula, although Trumpler 14 is not as massive and as large as Trumpler 16. About stars have been identified in Trumpler 14.〔 〕 and the total mass of the cluster is estimated to be 4,300 M⊙. ==Age== It is one of the youngest known star clusters, estimates range from 300 to 500 thousand years old.〔 For comparison, the massive super star cluster R136 is about 1 to 2 million years old., and the famous Pleiades is about 115 million years old.〔 〕 Due to its location within the inner parts of the Carina Nebula, Trumpler 14 is currently undergoing a massive star formation. As a result, the star cluster exhibits many stars of late O to early A spectral type, which are very massive (at least 10 solar masses), short-lived and hot (). The most prominent star is the supergiant HD 93129A, one of the most luminous stars in the Galaxy. 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「Trumpler 14」の詳細全文を読む スポンサード リンク
