翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Pre-stellar core ： ウィキペディア英語版 Pre-stellar core Pre-stellar cores are the nurseries of new stars, and are an early phase in the formation of low-mass stars, before gravitational collapse produces a central protostar. The spatial distribution of pre-stellar cores shows the history of their formation, and their sensitivity to the physics controlling their creation. Most of our Galaxy's star formation takes place in clusters and groups within large molecular clouds. These clouds are often turbulent, showing supersonic line widths and complex magnetic fields which play crucial roles in cloud physics. The properties of pre-stellar cores within molecular clouds aid understanding of the large-scale physical processes dictating star formation.〔(The Mass Distribution and Lifetime of Prestellar Cores in Perseus, Serpens, and Ophiuchus )〕 ==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「Pre-stellar core」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.
