Chushiro Hayashi (林 忠四郎, Hayashi Chūshirō, July 25, 1920 – February 28, 2010) was a Japanese
Hayashi was born in Kyoto and enrolled at the Imperial University of Tokyo in 1940, earning his BSc in Physics after 2½ years, in 1942. He was conscripted into the navy[1] and, after the war ended, joined the group of Hideki Yukawa at Kyoto University. He was appointed a professor at Kyoto University in 1957.[1]
He made additions to the Big Bang nucleosynthesis model that built upon the work of the classic Alpher–Bethe–Gamow paper.[2] Probably his most famous work was the astrophysical calculations that led to the Hayashi tracks of star formation,[3] and the Hayashi limit that puts a limit on star radius. He was also involved in the early study of brown dwarfs, some of the smallest stars formed.[4]
He retired in 1984 and died from pneumonia at a Kyoto hospital on February 28, 2010.[5][6]
