翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク HIP 79431 b ： ウィキペディア英語版 HIP 79431 b HIP 79431 b is an extrasolar planet discovered by the W. M. Keck Observatory in 2010. The planet is found in an M type dwarf star catalogued as HIP 79431 and is located within the Scorpius constellation approximately 47 light years away from the Earth. Its orbital period lasts about 111.7 days and has an orbital eccentricity of 0.29. The planet is the 6th giant planet to be detected in the Doppler surveys of M dwarfs and is considered to be one of the most massive planets found around M dwarf stars.〔(【引用サイトリンク】url= http://www.deepfly.org/TheNeighborhood/MDwarfPlanets.html )〕〔(【引用サイトリンク】url= http://exoplanet.eu/planet.php?p1=HIP+79431&p2=b )〕〔(【引用サイトリンク】url= http://planetquest1.jpl.nasa.gov/atlas_espanol/atlas_profile.cfm?Star=520 )〕 ==Observations== HIP 79431 b is located in orbit around a star whose metallicity had been challenging to be assessed due to the uncertainties within the molecular data line however it has not been typical for M Dwarfs to have strong emissions from the core data lines. This led to the inclusion of the HIP 79431 star to the KECK program in April 2009 as part of the exoplanet studies for low mass stars. During this study, 13 Doppler measurements of the star were done over a 6-month period using the High Resolution Echelle Spectrometer (HIRES). The exposure times used in its observation was 600 seconds which yielded a signal-to-noise ratio of just under 100. Each program observation required the use of iodine absorption lines in order to model the wavelength scale as well as the instrumental profile of the telescope and spectrometer optics. The Doppler experiments derived radial velocities fit the Keplerian model showing an unambiguous signal and orbital parameters which best fit planetary gravitational pull, this revealed the presence of the planet HIP 79431 b. However, there is no evidence that any additional planets was found. 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「HIP 79431 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.
