Knowra Fred Hoyle Fred Hoyle Fred Hoyle (1915–2001) was an English astronomer and science-fiction writer who helped develop stellar nucleosynthesis theory and coined the term “Big Bang.”
William Alfred Fowler : An American nuclear physicist who shared the 1983 Nobel Prize in Physics for research on element formation in stars. Fowler collaborated with Hoyle on the landmark account of how stars produce chemical elements.
Stellar nucleosynthesis : The formation of chemical elements through nuclear reactions inside stars and during stellar explosions. Hoyle helped establish how stellar processes make elements heavier than helium.
Steady-state model : A cosmological model in which the expanding universe maintains constant average density through continuous matter creation. Hoyle helped formulate and defend this alternative to an evolving universe with a finite beginning.
B2FH paper : A 1957 review by Margaret and Geoffrey Burbidge, William Fowler, and Fred Hoyle on the origin of chemical elements in stars. This landmark paper consolidated the theory of stellar nucleosynthesis associated with Hoyle.
Geoffrey Burbidge : An English-born astrophysicist known for research on quasars, galaxies, and the origin of chemical elements. Burbidge coauthored the 1957 paper that set out stellar element formation with Hoyle.
Triple-alpha process : A nuclear reaction sequence in which three helium-4 nuclei combine to form carbon-12. Hoyle predicted an excited carbon-12 state that makes this reaction proceed rapidly enough in stars.
Big Bang : The cosmological model that describes the universe’s expansion from an early hot, dense state. Hoyle coined its name while criticizing the model, though the term outlasted his opposition.
Radio astronomy : The branch of astronomy that studies celestial objects through their radio-frequency emissions. Hoyle supported radio astronomy as a means of testing astronomical theories and studying the universe.
Margaret Burbidge : A British-American astronomer whose research advanced stellar spectroscopy, galaxies, and the origin of chemical elements. She coauthored the stellar nucleosynthesis paper that became closely associated with Hoyle’s work.
Hoyle state : An excited energy state of the carbon-12 nucleus that enhances carbon production in stars. This state, predicted by Hoyle, explains how helium fusion can produce abundant carbon.
