翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク R Scuti ： ウィキペディア英語版 R Scuti R Scuti (''R Sct'') is a star in the constellation of Scutum. It is a yellow supergiant and is a pulsating variable known as an RV Tauri variable. It was discovered in 1795 by Edward Pigott at a time when only a few variable stars were known to exist. ==Observation== R Sct is the brightest of the RV Tau-type stars〔 and the American Association of Variable Star Observers (AAVSO) contains over 110,000 observations of this star.〔 At its brightest it is visible to the naked eye, and at its dimmest can be located with good binoculars.〔 In the sky it is about 1 degree northwest of the Wild Duck Cluster (Messier 11).〔 RV Tauri variables often have somewhat irregular light curves, both in amplitude and period, but R Scuti is extreme. It has one of the longest periods known for an RV Tau variable, and the light curve has a number of unusual features: occasional extreme minima; intermittent standstills with only small erratic variation that may last for years; and periods of chaotic brightness changes. 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「R Scuti」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.
