WebAfter millions of years, immense pressures and temperatures in the star’s core squeeze the nuclei of hydrogen atoms together to form helium, a process called nuclear fusion. Nuclear fusion releases energy, which heats the star and prevents it from further collapsing under the force of gravity.

WebThe stellar nuclear fusion process beings by hydrogen atoms fusing together to form helium. If the initial mass of the star is less than ~0.4 M, where M is the mass of our sun, then helium will be the final product. As the star fuses hydrogen, the helium will convect away from the core and allow more hydrogen to fuse.
