The Bruce Medalists: Chushiro Hayashi (296 words)
Hayashi showed that at the high temperatures characteristic of the very early universe, electron-positron pair production had to be taken into account, and this led to revisions in the estimate of the early neutron-proton ratio and a better value for the ultimate abundance of helium in the universe.
Hayashi was one of the pioneers in modeling stellar evolution in the 1950s and ’60s.
Hayashi has also worked on the formation of low-mass stars—he and Takenori Nakano made one of the earliest studies of what are now called brown dwarfs—and he has investigated the formation of the solar system and of the earth and its atmosphere.
