Olin Jeuck harrows
Olin Jeuck Eggen (born July 9, 1919 in Wisconsin , † October 2, 1998 in Canberra ) was an American astronomer .
Live and act
Eggen was one of the best observing astronomers of his time. In 1962, together with Donald Lynden-Bell and Allan Sandage, he published the thesis that the Milky Way was formed from a gas cloud. This thesis is known today as the ELS model (Eggen – Lynden-Bell – Sandage). He was the first to guess that stars move in groups. In 1985 he was awarded the Henry Norris Russell Lectureship for his life's work .
Eggen played a somewhat less glorious role in the historical appraisal of the Neptune discovery. The planet was discovered by Johann Gottfried Galle after Urbain Leverrier predicted its position , although English astronomers - James Challis and George Biddell Airy - searched for it after John Couch Adams made a prediction. Airy had compiled a great deal of material on British activities in a 'Neptune File', but this file, kept in Greenwich , had not been found since the late 1960s. After Eggen's death, 105 kg of archive material was found in the drawers of his desk in Chile, including a. also the lost (according to another reading “borrowed”) Neptune Act.
From 1966 to 1977 Eggen headed the Mount Stromlo Observatory in Australia.
