翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tau Canis Majoris ： ウィキペディア英語版 Tau Canis Majoris Tau Canis Majoris (τ CMa, τ Canis Majoris) is an eclipsing spectroscopic binary in the constellation Canis Major and the brightest star of an open cluster designated NGC 2362. Approximately 3200 light years from Earth, the star is actually a multiple star system with some massive components. This star is sometimes known as the 'Mexican Jumping Star' by amateur astronomers, because it can appear to 'jump around' with respect to the other stars in the cluster because of its marked contrast in brightness.〔(The Mexican Jumping Star )〕 τ Canis Majoris is classified as an O-type blue supergiant with a mean apparent magnitude of +4.37. It is a Beta Lyrae type variable star with a period of 1.28 days, over which time its brightness varies from magnitude +4.32 to +4.37. It might be that one or more components are intrinsically variable. The main star can be split into components of apparent magnitude 4.9 and 5.3 0.15 arcseconds apart, with a magnitude 10 component 8 arcseconds distant. The brighter of these is composed of three stars- two egg-shaped stars that are 0.1 astronomical unit (AU) apart and orbit each other every 1.28 days and a third that orbits this pair every 155 days at a distance similar to that of Jupiter from our Sun. The 5.3 magnitude star lies 223 AU distant from the group and takes more than a year to orbit the others, and the 10th magnitude star is 13,000 AU distant. Combined, the four close stars have a combined mass 80 times that of the Sun and shine with 500,000 times its luminosity, but little is known of their individual properties.〔 ==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「Tau 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.
