Supernovae are energetic events that occur when massive stars run out of nuclear fuel and collapse. Explosive nucleosynthesis creates heavy elements and temperatures of billions of degrees. Supernovae are responsible for creating elements heavier than iron, while stellar nucleosynthesis creates hydrogen and helium. The Big Bang nucleosynthesis fused hydrogen atoms into helium nuclei, resulting in […]
Stellar nucleosynthesis creates most elements in the periodic table. The Big Bang created 80% hydrogen and 20% helium. Proton-proton chain and CNO cycle are types of hydrogen burning. Heavier elements are formed through alpha, carbon, neon, oxygen, and silicon burning. A star can collapse into a neutron star or black hole. Stellar nucleosynthesis is the […]
