Alfred Weigert

from Wikipedia, the free encyclopedia

Alfred Weigert (born November 13, 1927 in Labes ; † December 13, 1992 in Hamburg ) was a German astronomer and astrophysicist.

After graduating from high school in Halle in 1947, he completed an apprenticeship as a machinist and then studied mathematics and physics and later also astronomy in Halle and Jena , where he received his doctorate in astronomy under Hermann Lambrecht (1908–1983) in 1957 ( nuclear structure and halo formation in comets ). In 1961, on the day the Wall was built in the GDR, he went to Munich to the Max Planck Institute for Astrophysics . In 1966 he completed his habilitation in Göttingen and in 1969 he became a professor in Hamburg .

After initially dealing with the interstellar medium and comets, he turned to the theory of stellar evolution in Munich (development to the red giant on the main sequence , Cepheids , nature of thermal pulses, development of binary star systems), which he studied with computer simulations, at the time pioneering achievements in competition to groups in the US. In Hamburg he dealt in particular with the mathematical uniqueness of the solutions of the non-linear partial differential equations that arise.

In 1991 he became a member of the Leopoldina .
