Chushiro Hayashi (Japanese: Lin Zhongsiro/Hayashi Chūshirō, July 25, 1920 - February 28, 2010), Japanese astronomer.HerotuOnForest locusName it after its name.
His most well-known achievement is that he proposed the forest track and forest limit.He was also involved in the study of how brown dwarfs formed.Retired in 1984.Became in December 1987Japanese Bachelor's Collegemember.
He died in Kyoto on February 28, 2010.

In astrophysical researchCosmic expansionThe process of early formation and final evolution of elements leading to the formation and evolution of stars and galaxies and the birth of the origin of the solar system is a great achievement.
They took into account the physical way and creativity, which is a theoretical understanding of space phenomena, especially in the research of star evolution. In the period of "Xiang" Lin's so-called brilliant star focus, it was found that there was a scene of star birth known as the world as a changed star.
With extensive efforts, the young generation in education and training, active in various fields, such as cultural command, is a major contribution to improving science and culture.

Born in Kyoto, he received his bachelor's degree in physics from Tokyo University in 1942.the Second World WarLater, he served as a research assistant in Hideki Tomokawa of Kyoto University and an associate professor of physics in Naniwa (Osaka Prefecture) University.He studied for a doctorate at Kyoto University and retired from 1954 to 1984.In 1950, he studied the nuclear synthesis of α β γ (Alf,Bette，Gamov）The model has made a significant contribution.He pointed out that under the high temperature characteristics of the early universe, the generation of electron positron pairs must be considered, which led to the revision of the estimate of the early neutron proton ratio and a better value of the final abundance of helium in the universe.In the 1950s and 1960s, he was one of the pioneers of star evolution modeling. His most famous models were his star formation model and the pre main sequence evolution model.He proved that they are completely convective, not inHydrostatic balance, before he found outMain sequence starOn the Herzpula Russell diagram, along the“Lin Zhongsirang's track”Until they reach the main sequence, that is, they shrink at near constant surface temperature.He also studied the formation of low mass stars. He and Takenori Nakano conducted the earliest research on brown dwarfs. He studied the formation of the solar system, the Earth and the atmosphere.He is the leader in building astrophysics in Japan, and some of the most important theorists are his former students.
