翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Kappa Andromedae b ： ウィキペディア英語版 Kappa Andromedae b Kappa Andromedae b is a substellar object and massive planet/brown dwarf orbiting Kappa Andromedae, a star in the Andromeda constellation, about 170 light years away. The object, nearly 13 times the mass of Jupiter, was directly photographed by the Subaru Telescope. There has been considerable debate as to whether Kappa Andromedae b is an exoplanet or a brown dwarf; and, until the question can be clarified, scientists have dubbed it the "Super-Jupiter" object. ==Discovery== Through the Strategic Explorations of Exoplanets and Disks with Subaru (SEEDS) survey, the Subaru Telescope, located atop Mauna Kea, Hawaii, astronomers were able to photograph Kappa Andromedae b by taking a near-infrared photograph of the parent star and processing it to reduce its light. Between January and July 2012, Subaru observed Kappa Andromedae using four separate infrared wavelengths, and when comparing photographs from January and July, the team of astronomers was able to determine that Kappa Andromedae and Kappa Andromedae b were gravitationally bound.〔 Through those photographs and other research by the Subaru team, a few details about the "Super-Jupiter" object have been revealed. The object's mass has been calculated as approximately 12.8 times Jupiter's mass, the host star's mass as 2.4 to 2.5 solar masses. The temperature of the object is estimated to be around 1700 kelvin, and, if seen up close, would appear reddish in color.〔 The object's distance from its parent star is about 1.8 times Neptune's distance from the Sun.〔 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「Kappa Andromedae b」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.
