Our best articles related to Stellar nucleosynthesis
Stellar nucleosynthesis occurs in stars during the process of stellar evolution. It is responsible for the generation of elements from carbon to iron by nuclear fusion processes. Stars are the nuclear furnaces in which H and He are fused into heavier nuclei, a process which occurs by...
The most important reactions in stellar nucleosynthesis: * Hydrogen burning: ** The proton-proton chain. ** The carbon-nitrogen-oxygen cycle. * Helium burning: ** The triple-alpha process. ** The alpha process. * Burning of heavier elements: ** Carbon burning process. ** Neon burning...

Stellar nucleosynthesis is the collective term for the nuclear reactions taking place in stars to build the nuclei of the elements heavier than hydrogen. Some small quantity of these reactions also occur on the stellar surface under various circumstances. For ...

” The Cornell Chapter was the founding branch of the organization and contributed a number of illustrious members like Hans Bethe, the German-American physicist who won the Nobel Prize in Physics in 1967 for his work on the theory of ...
The r-process was seen to be needed from the relative abundances of isotopes of heavy elements and from a newly published table of abundances by Hans Suess and Harold Urey in 1956. Among other things, this data showed abundance peaks ... iron peak is a local maximum in the vicinity of Fe (V, Cr, Mn, Fe, Co and Ni) on the graph “abundances of the chemical elements”. For elements before iron, nuclear fusion releases energy. For elements heavier than iron, nuclear ...

George Gamow (; August 19, 1968), born Georgiy Antonovich Gamov (Георгий Антонович Гамов), was a Russian-born theoretical physicist and cosmologist. He discovered alpha decay via quantum tunneling and worked on radioactive decay of the atomic nucleus, star formation, stellar nucleosynthesis, ...
Cosmic dust is a type of dust composed of particles in space which are a few molecules to 0.1& mm in size. Cosmic dust can be further distinguished by its astronomical location; for example: intergalactic dust, interstellar dust, interplanetary dust ...
B²FH (pronounced “B squared F H”) is the initials of Margaret Burbidge, Geoffrey Burbidge, William Fowler and Fred Hoyle, and refers to a well-known astrophysics paper titled “Synthesis of the Elements in Stars”, published in 1957; the article is so ...

During the early phases of the Big Bang, nucleosynthesis of hydrogen nuclei resulted in the production of hydrogen and helium isotopes, as well as very minuscule amounts (on the order of 10−10) of lithium and beryllium. There is argument about ...
