Bengt Edlén
Bengt Edlén (born November 2, 1906 , † February 10, 1993 ) was a Swedish astrophysicist .
Edlén was a professor at Lund University from 1944 to 1973 .
His main research area was the spectroscopic investigation of the solar corona . In 1940 he was able to explain spectral lines that had previously been assigned to an unidentified element - called coronium - as lines of multiple ionized iron. This interpretation was not immediately accepted as it would require a temperature of millions of degrees in the corona, but it later turned out to be correct.
He was awarded the gold medal of the Royal Astronomical Society in 1945 and the Henry Draper Medal in 1968 . In 1957 he was elected to the American Academy of Arts and Sciences . In 1972 he became a member ( associé étranger ) of the Académie des sciences in Paris.
