Kinds of exothermic fusion process :

• carbon burning (9 facts) - The stage when a star fuses carbon into heavier elements, making neon and magnesium. Carbon burning eventually occurs in all stars born with more than eight solar masses.
• helium burning (2 kinds, 15 facts) - The stage when a star fuses helium into carbon and oxygen. All stars born with more than half a solar mass eventually burn helium.
• hydrogen burning (8 kinds, 62 facts) - The fusion of hydrogen into helium and the process by which all main-sequence stars generate energy. Every star born with more than 0.08 solar masses burns hydrogen.
• neon burning (8 facts) - The stage in which a star burns neon into oxygen and magnesium.
• oxygen burning (8 facts) - The stage when a star fuses oxygen into silicon and sulfur. It occurs only in stars born with over eight solar masses.
• silicon burning (8 facts) - The end of the line for a high-mass star, silicon burning creates iron and other elements of similar mass and presages a supernova.
