Bengt Edlén (November 2, 1906, Gusum – February 10, 1993, Lund) was a Swedish professor of physics and astronomer who specialized in spectroscopy. He participated in solving ''the Corona Mystery'': unidentified spectral lines in the sun's spectrum were speculatively believed to originate from a hitherto unidentified chemical element termed coronium. Edlén later showed that those lines are from multiply ionized iron (Fe-XIV). His discovery was not immediately accepted, since the alleged ionization required a temperature of millions of degrees. Later such solar corona temperatures were verified. He also made an important contribution in analyzing spectra of Wolf-Rayet stars. Edlén was professor at Lund University from 1944 to 1973. He was elected a member of the Royal Swedish Academy of Sciences in 1947. He graduated from high school in Norrköping in 1926 and entered the University of Uppsala, eventually graduating with a PhD in 1934. Bengt Edlén received the Gold Medal of the Royal Astronomical Society 1945 for the solution of the Corona Mystery,〔(【引用サイトリンク】url=http://www.ras.org.uk/awards-and-grants/awards/268 )〕 the Howard N. Potts Medal in 1946 for researches in the extreme ultraviolet, and the Henry Draper Medal of the National Academy of Sciences〔(【引用サイトリンク】url=http://www.nasonline.org/about-nas/awards/henry-draper-medal.html )〕 in 1968. ==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「Bengt Edlén」の詳細全文を読む スポンサード リンク
