Late in the evolution of massive stars, fusion reactions create cores within cores within cores, etc.  Hydrogen fusion occurs in a layer around a layer of helium fusion which occurs around of layer of carbon fusion... around oxygen fusion... around neon fusion... etc.  The deeper you go, the heavier elements you find made, and the higher the temperature needed to sustain that particular fusion reaction.
