The slow neutron-capture process (the s-process) is one of the nucleosynthesis processes that occurs in stars. It results in about half of the elements heavier than iron in the universe. Two important ...

Although the periodic table is filled with elements, nuclear fusion at the center of stars can only produce elements with atomic masses lower than iron—after than, neutron captures processes known as ...

The cosmic site where the heaviest chemical elements such as lead or gold are formed has likely been identified: Ejected matter from neutron stars merging in a violent collision provides ideal ...
