High mass stars form very rapidly in less than 100000 years a collapsing proto star can reach the Main Sequence Massive stars at all stages of their lives live their lives in the very fast lane The pressure on their cores is so great far more powerful nuclear reactions power them than the simpler protonproton chain that medium and low mass stars use to generate their energy Massive stars instead use the CarbonNitrogenOxygen or CNO cycle to release their energy Nuclei of carbon absorb protons in a multistage process where the carbon acts like a catalyst and at the end of the process the oxygen nucleus ejects the newly formed helium nucleus leaving See Answer
