Career
Hayashi received his bachelor's degree in physics from the University of Tokyo in 1942 . After staying in Tōkyo, as an employee of Hideki Yukawa in 1945 at the University of Kyoto and at the Naniwa University in Osaka , he returned to Kyoto as a professor.
In 1950 he made an important contribution to the theory of the Big Bang by showing that the model proposed by Ralph Alpher and George Gamow ( Alpher-Bethe-Gamow theory ) had to be supplemented by the formation of electron - positron pairs.
Hayashi developed the first models of contracting young stars at a stage before they even reached the main sequence of the Hertzsprung-Russell diagram . The Hayashi line is named after him.
