Edwin Salpeter
Edwin Ernest Salpeter (born December 3, 1924 in Vienna , † November 25, 2008 in Ithaca , New York ) was an Austro-Australian and American astrophysicist.
Life
As a teenager, Salpeter emigrated from Austria to Australia in 1939 , where he studied physics and mathematics at the University of Sydney . He received his doctorate in 1948 at the University of Birmingham in England, where he worked with Rudolf Peierls . From 1948 he worked at Cornell University , among others with Hans Bethe , on problems of quantum electrodynamics and nuclear physics and later in many areas of theoretical astrophysics . With Bethe he developed the Bethe-Salpeter equation for bound states in quantum field theory. Most recently, he was the James Gilbert White Distinguished Professor of the Physical Sciences at Cornell University.
Saltpeter studied nuclear reactions inside stars and the evolution of stars. In 1955 he derived the initial mass function (IMF) of stars, which states the numerical proportions in which stars of different masses are formed.
In 1964, along with Jakow Seldowitsch, he was one of the first to propose accretion disks around black holes as models for quasars and active galaxies. In 1993 he was elected a foreign member of the Royal Society .
Saltpeter died of leukemia shortly before his 84th birthday .
