Stellar mass loss is a phenomenon observed in some massive stars. It occurs when a triggering event causes the ejection of a large portion of the star's mass. Stellar mass loss can also occur when a star gradually loses material to a binary companion or into interstellar space. ==Causes== A number of factors can contribute to the loss of mass in giant stars. A few are listed below: *Gravitational attraction of a binary companion *Coronal mass ejection-type events *Ascension to red giant or red supergiant status 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「Stellar mass loss」の詳細全文を読む スポンサード リンク
