Bengt Edlén (
November 2 ,1906 –February 10 ,1993 ) was a Swedish professor of physics and astronomer specialized inspectroscopy . He participated in solving the Corona Mystery: unidentified spectral lines in thespectrum ofsun was speculatively believed to originate from a hitherto unidentifiedchemical element coinedCoronium , but instead revealed, by Edlén, to be lines from several times ionizediron . His discovery wasn't immediately accepted, since the alleged ionization required a temperatur of million degrees - later such solar corona temperatures were verified.He also made an important contribution in analyzing spectra of
