  • The life cycle of stars
    • Gravtiational forces pull clouds of dust and gas together to form a protostar
      • The protostar becomes denser and the nuclei of hydrogen atoms and other light elements start to fuse together. Energy is released in the process so the core gets hotter and brighter.
        • Stars radiate energy because of hydrogen fusion in the core.
          • this stage can continue for years untill the star runs out of hydrogen nuclei.
            • The star is stable because the inward force of gravity is balanced by the outward force of radiation from the core and is called a main sequence star.
