Another way to understand convection comes from examining the relevant equations of stellar … WebStellar Structure and Evolution. Stars are the source of almost all of the light our eyes see in the sky. Nuclear fusion is what makes a star what it is: the creation of new atomic nuclei within the star’s core. Many of stars’ properties — how long they live, what color they appear, how they die — are largely determined by how massive ...
