Chushiro Hayashi

Japan / July 25, 1920
Astrophysicist; Professor Emeritus, Kyoto University

An astrophysicist who introduced the knowledge and methods of fundamental physics into analysis of astronomical phenomena, applying scientific principles from such fields as nuclear physics and fluid dynamics. Through studies of stellar evolution and the solar system, he developed theories explaining many astronomical phenomena and contributed immeasurably to the maturation of modern astrophysics.
