Armin Joseph German

from Wikipedia, the free encyclopedia

Armin Joseph Deutsch (born January 25, 1918 in Chicago , Illinois , † November 11, 1969 in Pasadena , California ) was an American astronomer .

Life

Deutsch received his Bachelor of Science degree from the University of Arizona in 1940 and received his PhD from the University of Chicago in 1946 with a thesis on variable A-stars that he had done at the Yerkes Observatory . During World War II , he served as an instructor for the United States Air Force in Chanute Field , Illinois, from 1942 to 1944 . From 1944 he was an assistant or lecturer at the Yerkes Observatory (1944-1946), Ohio State University (1946-1947) and Harvard University (1947-1950). From 1951 until his death he worked at the Mount Wilson and Palomar Observatory in Pasadena.

Services

Armin J. Deutsch was mainly concerned with spectroscopy and the investigation of hot stars ( A stars ), especially those with strong magnetic fields and uneven distribution of heavy elements such as europium on the surface.

Together with Jesse Greenstein and Judith Cohen , he examined in particular the star α 2 Canum Venaticorum . He showed that the changes in the parameters of Ap stars , such as brightness or absorption line profiles, can be explained by a model in which the axis of the magnetic field is not parallel to the axis of rotation.

Together with Guglielmo Righini , he discovered cold regions in the solar corona by observing the total solar eclipse of July 20, 1963 .

Deutsch also wrote science fiction stories. His short story A Subway Named Mobius appeared in Astounding Science Fiction in 1950 and won the Retro Hugo Award in 2001. It served as a template for the films Moebius (Germany 1992) and Moebius (Argentina 1996).

Honor

In 1970 the lunar crater Deutsch was named after him.
