ASTR 1102 Lecture : Nuclear Fusion Notes
Document Summary
Sun has enough hydrogen (h) to last about for 5 billion more years of fusion. Triple alpha process (helium nuclei building carbon and oxygen. Inside the sun, the density is so high that photons interact constantly. At the base of the photosphere, the density drops enough photons to escape. When you create a photon in the core, it takes a random path to escape (can take up. Measure vibrations in the sun to 200,000 years after you"ve made your first photon) Almost massless particles that don"t really interact with anything. They will not go faster than the speed of light. 6. 5 trillion pass through your hand every second.
