In the past it was a double star system. The other star has fallen into a black hole and this star was greatly accelerated by the black hole. Christened by the astronomer Warren Brown as the Outcast Star, it is the first discovered member of a class of objects named hypervelocity stars. ==Discovery== It was discovered at the MMT Observatory of the Harvard-Smithsonian Center for Astrophysics (CfA), by astronomers Warren Brown, Margaret J. Geller, Scott J. Kenyon and Michael J. Kurtz. Scientists theorize that the star was ejected out of a binary star system approximately 80 million years ago when it encountered a black hole in the center of the Milky Way 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「SDSS J090745.0+024507」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.
