Como explorar Stellar Nucleosynthesis 3D Explorer

Open the cutaway and click each shell to see how a massive star forges the elements from hydrogen down to iron.

  1. Open https://freetoolonline.com/space-3d/stellar-nucleosynthesis.html and wait for the onion cutaway.
  2. Read the overview: the p-p chain (26.7 MeV), the CNO cycle (25.0 MeV), and the iron peak.
  3. Click each shell from the hydrogen envelope inward to see its reaction and temperature.
  4. Jump to the iron core to see why fusion stops there.
  5. Compare with Star Lifecycle 3D for the evolution over time, or Sun Structure 3D for energy transport zones.
