The energy of the stars comes from nuclear fusion<span> processes. For stars like the sun which have internal temperatures less than fifteen million Kelvin, the dominant fusion process is </span>proton-proton fusion<span>. For more massive stars which can achieve higher temperatures, the </span>carbon cycle<span> fusion becomes the dominant mechanism. For older stars which are collapsing at the center, the temperature can exceed one hundred million Kelvin and initiate the helium fusion process called the </span>triple-alpha process<span>.</span>
It's not right.
