Star development and element formation – basic principles
How it works
Stars form from gas and dust clouds, go through various stages of development, and generate new elements in their interior through nuclear fusion. The development of a star depends largely on its initial mass. Stars with smaller mass end as white dwarfs; massive stars can end as neutron stars or black holes. Elements up to about iron are formed mainly by fusion in stars. Many heavier elements are formed by neutron capture, for example in giant stars, in supernovae, or in neutron star mergers, and are distributed into space.
The development of a star is determined above all by its initial mass. In stars, new elements up to about iron are formed by nuclear fusion; many even heavier elements are formed by neutron capture in evolved stars or in extreme events such as supernovae and neutron star mergers.
