In modern theory, there are a number of [[astrophysical]] processes which are believed to be responsible for nucleosynthesis in the universe. The majority of these occur within the hot matter inside stars. The successive [[nuclear fusion]] processes which occur inside stars are known as hydrogen burning (via the [[proton-proton chain]] or the [[CNO cycle]]), [[Helium fusion|helium burning]], [[Carbon burning process|carbon burning]], [[Neon burning process|neon burning]], [[Oxygen burning process|oxygen burning]] and [[silicon burning process|silicon burning]]. These processes are able to create elements up to iron and nickel, the region of the isotopes having the highest [[binding energy]] per nucleon. Heavier elements can be assembled within stars by a neutron capture process known as the [[S-process|s process]] or in explosive environments, such as [[supernova]]e, by a number of processes. Some of the more important of these include the [[R-process|r process]], which involves rapid neutron captures, the [[Rp-process|rp process]], which involves rapid proton captures, and the [[P-process|p process]] (sometimes known as the gamma process), which involves [[photodisintegration]] of existing nuclei.
