Question

How are the processes of Hydrogen Burning and Alpha Fusion different? Write 1-2 sentences.(2 points)

Answer 1

Hydrogen burning primarily involves the fusion of hydrogen nuclei (protons) into helium in stars, typically through the proton-proton chain or the CNO cycle, releasing energy in the process. Alpha fusion, on the other hand, specifically refers to the fusion of helium nuclei (alpha particles) to form heavier elements, such as carbon or oxygen, occurring in the later stages of stellar evolution when core temperatures are sufficiently high.
