Yoichiro Nambu was Hayashi's college classmate at UTokyo.[2]
He made additions to theBig Bangnucleosynthesis model that built upon the work of the classicAlpher–Bethe–Gamow paper.[3]Probably his most famous work was the astrophysical calculations that led to theHayashi tracks of star formation,[4] and theHayashi limit that puts a limit on star radius.He was also involved in the early study ofbrown dwarfs, some of the smallest stars formed.[5]
