  1. 2. This limit is 1.44 solar masses, the maximum stable mass of a white dwarf before further collapse

  3. 5. After a supernova for core masses greater than 3 solar masses
  4. 8. The theoretical final stage after a white dwarf
  5. 9. The next stage of our sun's life
  6. 11. Where the highest naturally made elements on the periodic table originate from
  7. 13. The birthplace of a star, a cloud of dust and gas
  8. 14. This means no fusion

  1. 1. The most stable part of a star's life cycle
  2. 3. In the main sequence stage, when the inward gravitational attraction is equal to the outward force from radiation pressure from fusion, the star is in _________________
  3. 6. This pressure prevents further collapse of a neutron star, unless above 1.44 solar masses
  4. 7. In this early stage of a star's life, there is no fusion
  5. 10. This radiation is being emitted from a white dwarf
  6. 12. The process by which hydrogen combined to make helium
