How are chemical elements created in stellar nucleosynthesis?
Process by which the natural abundances of the chemical elements within stars change due to nuclear fusion reactions. Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars.
What makes up the nucleus of a neutron star?
An artist’s depiction of a neutron star merger. These mergers produce heavy elements like gold and platinum in abundance. Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons.
Why do Stars fuse light elements to heavier elements?
The amounts of total mass in elements heavier than hydrogen and helium (called 'metals' by astrophysicists) remains small (few percent), so that the universe still has approximately the same composition. Stars fuse light elements to heavier ones in their cores, giving off energy in the process known as stellar nucleosynthesis.
When did stellar nucleosynthesis occur in the Big Bang?
Stellar nucleosynthesis has occurred since the original creation of hydrogen, helium and lithium during the Big Bang. As a predictive theory, it yields accurate estimates of the observed abundances of the elements.
