  • Burbidge, Burbidge, Fowler and Hoyle worked out the nucleosynthesis processes that go on in stars, where the much greater density and longer time scales allow the triple-alpha process (He+He+He -> C) to proceed and make the elements heavier than helium. But BBFH could not produce enough helium. — “Big Bang Nucleosynthesis”, astro.ucla.edu
  • Nucleosynthesis Activities. A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning" Nucleosynthesis requires a high-speed collision, which can only be achieved with very high temperature. — “NASA's Cosmicopia - Basics - Composition - Nucleosynthesis”, helios.gsfc.nasa.gov

  • Nucleosynthesis happens! Nucleosynthesis in 2nd Generation Stars. pppp 4He + 2e + 2 . Catalysed by C, N, O trace density from a previous SN Explosive Nucleosynthesis. Free neutrons and , -particles fuel the endothermic fusion to heavier elements. — “Nucleosynthesis II”,
  • Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons). The primordial preexisting nucleons were formed from the quark-gluon plasma of the Big Bang as it cooled below ten million degrees. — “Nucleosynthesis”,
  • Nucleosynthesis in the Early Universe. The term nucleosynthesis refers to the formation of heavier elements, atomic nuclei with many protons and neutrons, from the fusion of lighter elements. This process of light element formation in the early universe is called "Big Bang nucleosynthesis" (BBN). — “WMAP Big Bang Elements Test”, map.gsfc.nasa.gov
  • Cosmic nucleosynthesis is the process by which atomic nuclei first formed in the Universe. After nucleosynthesis, the Universe contained mainly nuclei of hydrogen and helium-4, with additional trace amounts of deuterium, helium-3, and lithium-7. The success of nucleosynthesis theory is one of the. — “nucleosynthesis - History, Cosmic cookery: the basic picture”,
  • However, now that you know about stellar nucleosynthesis, I need to be more careful about what is being created from scratch and what is being re-used. Although the particulars of various nucleosynthesis processes are beyond the scope of this website, it is important to note a couple of things:. — “Lives and Deaths of Stars”,
  • What interested Gamow was the problem of nucleosynthesis. That is, the question of how nuclei of all the chemical elements came to be formed. A little later, when we come to discuss nucleosynthesis – the process in which nuclei of elements such as helium and heavy hydrogen (deuterium). — “Open Questions: The Big Bang”,
  • This is a page in The Physics Hypertextbook. It is a work in progress. big bang nucleosynthesis.
