翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク R Canis Majoris ： ウィキペディア英語版 R Canis Majoris R Canis Majoris is an eclipsing interacting binary star system in the constellation Canis Major. It varies from magnitude 5.7 to 6.34. The system is unusual in the low ratio between the main two components and shortness of the orbital period.〔 ==Eclipse timings== Eclipse timings for R Canis Majoris have been being measured since 1887, and whilst at present the time period appears constant at 1.1359 days, periodic quasi-sinusoidal variations of the eclipse arrival times have been taking place with a periodicity of around 93 years. This has led to the suggestion that there exists a third non-eclipsing body in the system whose gravitational pull is responsible for these variations.〔“Astrometric and light-travel time orbits to detect low-mass companions: a case study of the eclipsing system R Canis Majoris” "Ribas I, Arenou F, & Guinan EF - The Astronomical Journal, 123:2033-2041, 2002 April〕 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 Canis Majoris」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.
