stellar

Personally, I think stars with different degrees of difficulty in element fusion will lead to the elements that are difficult to fuse falling to the core and gradually stratification. Hydrogen fusion turns into helium. Because it is difficult to fuse and heavier than hydrogen, the helium layer will gradually enter the interior of the sun. With the passage of time, the helium layer will gradually wrap the inner layer, and the local change of hydrogen fusion pressure will have the probability to detonate the inner helium layer, resulting in more…
