It is a semi-regular pulsating star that varies in apparent magnitude from 2.60 down to 6.00 with a period of 140.83 days.〔 The variation in light may be caused by a combination of radial pulsations in the star's atmosphere and by dimming from circumstellar dust.〔 This is most likely an asymptotic giant branch star that has passed through the main sequence and is evolving to become a white dwarf. It is shedding mass at the rate of about −9 solar masses per year.〔 Recently the star has had an apparent magnitude range of about 6.9 to 8.〔 L2 Puppis has a visual 10th magnitude companion about a minute of arc away.〔 ==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「L2 Puppis」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.
