MWC 147 also known as HD 259431 is a star 2,600 light years away the constellation of Monoceros〔( It Takes A Very Large Telescope To See Inside MWC 147 ).〕 This star is classed as a ''young stellar object'' and has been instrumental in helping astronomers undestand the formation of stars.〔Stefan Kraus, Thomas Preibisch, Keiichi Ohnaka, (Detection of an inner gaseous component in a Herbig Be star accretion disk: Near- and mid-infrared spectro-interferometry and radiative transfer modeling of MWC 147 ).( Astrophysical Journal. Nov 2007).〕 A large star, with a large surrounding dust cloud,〔T. Bagnoli, R. van Lieshout, L. B. F. M. Waters, G. van der Plas, B. Acke, H. van Winckel, G. Raskin, P. D. Meerburg ( An Inner Gaseous Disk around the Herbig Be Star MWC 147 ) (7 Oct 2010).〕 MWC 147 has given astronomers a clear picture of the mechanics of the accretion processes that form stars.〔(The Region Around MWC 147 ) at European Space Agency website.〕 Star MWC 147 was observed in the near and mid-infrared. The near infrared studies showed dust matter at a temperature of several thousand degrees Kelvin in the innermost regions of the protoplanetary disk. In the mid-IR were lower temperatures. These observations showed that the disk around the star disk extends over 100AU. The resulting research model assumes that the star increasing in mass at a rate 7/1000000 solar masses per year or the equivalent of about two Earth masses per year. MWC has a mass of 6.6M ☉ and is younger age than 500 000 years. This means that the life of this star is expected to be only about 35 million years. ==Characteristics== The star is found in the night sky at RA 06 h 33 m 05.19 and Dec 10 ° 19 '19.9869 " and is 14 125 K and has a Spectral type of B6ep.〔(MWC+147 ) at simbad database.〕 It is also known as J06330519 + 1019199, HD 259431, HIP 31235 and SAO 95823 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「HD 259431」の詳細全文を読む スポンサード リンク
