Best answer: all elements heavier than beryllium, including oxygen, are originally created through stellar nucleosynthesis (from fusion in the cores of massive stars [for elements up to iron]) or supernova nucleosynthesis (fusion during the explosion of a massive star [for all transferric elements]). A discussion of stellar nucleosynthesis the cno cycle is so called, for it uses carbon, nitrogen, and oxygen as catalysts to fuse hydrogen into helium, but the . Starters carbon, nitrogen and oxygen (cno cycle) 4) continued nucleosynthesis through fusion of hydrogen, helium, carbon, nitrogen, and.
In stars, nitrogen is fused with hydrogen to form oxygen (stellar nucleosynthesis) when starts explode, elemental oxygen (along with many other elements are ejected) and the oxygen can chemically react with a wide variety of other elements. Big bang nucleosynthesis to do that we need carbon and oxygen and nitrogen and silicon and chlorine and every other naturally occurring element almost all the .

Supernova nucleosynthesis within exploding stars by fusing carbon and oxygen is responsible for the abundances of elements between magnesium (atomic numb express .
Of the elements strictly synthesized in stars, oxygen is by far the most abundantly produced we review the nucleosynthesis and galactic chemical evolution of this important element. The properties of nuclei from oxygen to nickel near the neutron-stability boundary are studied in the self-consistent theory of finite fermi systems the position of this part of the neutron-stability boundary is calculated and found to be in agreement with available experimental data the stability .

This step first generates 12 c, and then 16 o, which is the dominant product of the helium burning cycle 16 o is the substrate for the next phase of the 40 k production pathway, explosive oxygen . With regard to the nucleosynthesis, the final concentration of iron group elements was determined to be comparable to that of model s135u there is only a small concentration of intermediate-mass elements in the final stages, which confirms that indeed cno nuclei were burned all the way to iron. Nucleosynthesis definition nucleosynthesis is the process by which heavier chemical elements are synthesized in the interiors of stars from hydrogen oxygen into .
Stellar nucleosynthesis evolution and nucleosynthesis 18 energy production and neutrino emission oxygen and nitrogen (cno) these nuclei may induce a chain of. Nucleosynthesis or nucleogenesis, in astronomy, production of all the chemical elements  from the simplest element, hydrogen, by thermonuclear reactions within stars, supernovas, and in the big bang at the beginning of the universe (see nucleus  nuclear energy ). 1 nucleosynthesis and chemical evolution of oxygen bradley s meyer department of physics and astronomy clemson university clemson, sc 29634 larry r nittler and ann n nguyen. Onuclear decay of 56co, produced during supernova nucleosynthesis, powers the light from supernova remnants temperatures required for oxygen burning. S-process may come from carbon and oxygen burning and the subsequent photodisitengration at even higher temperature there may be some neutron production by side reactions during.
Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements all of the atoms in the universe began as hydrogen fusion inside stars transforms hydrogen into helium, heat, and radiation heavier . Stellar nucleosynthesis is the theory explaining the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions between atoms within the stars stellar nucleosynthesis has occurred continuously since the original creation of hydrogen, helium and lithium during the big bang. Astronomy cast episode 107: nucleosynthesis: elements from stars on during the big bang nucleosynthesis carbon-nitrogen-oxygen cycle which is the next cycle .
