Hayashi, Chushiro (1920–2010)




Chushiro Hayashi
Japanese astrophysicist at Kyoto University who did important work on the early evolution of stars and of the universe. In 1950 he was the first to offer a variant of the hot Big Bang model as put forward in 1946 by George Gamow and colleagues in the famous "Alpher-Bethe-Gamow" theory. He is best remembered, however, for his discovery of the almost temperature-independent early evolution of pre-main-sequence stars along what has become known as the Hayashi track.
