Chushiro Hayashi (林 忠四郎 Hayashi Chūshirō, July 25, 1920 – February 28, 2010) was a Japanese astrophysicist. Hayashi tracks on the Hertzsprung–Russell diagram are named after him.
He earned his B.Sc in physics at the Imperial University of Tokyo in 1942. He then worked as a research associate under Hideki Yukawa at Kyoto University. He made additions to the big bang nucleosynthesis model that built upon the work of the classic Alpher–Bethe–Gamow paper.[1] Probably his most famous work was the astrophysical calculations that led to the Hayashi tracks of star formation,[2] 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.[3] He retired in 1984.
He won the Eddington Medal in 1970, the Kyoto Prize in 1995, and the Bruce Medal in 2004.
Chushiro Hayashi died from pneumonia at a Kyoto hospital on February 28, 2010.[4][5]
