ASTROPHYSICS - Coggle Diagram

- - - - The star enters a long stable period, which typically lasts several billion years
      - During this period, the outward pressure caused by thermal expansion balances the force of gravity pulling everything inwards
    - - Star about the same size as the sun.
    - - The force of gravity pulls the gas and dust together to form a protostar.
      - The force of gravity pulls the gas and dust together to form a protostar.
    - - There are no more light element to use and it collapses
    - - Stars initially form from a cloud of dust and gas called nebula.
    - - The star will end its life in this stage
  - - - Star runs out of hydrogen to fuel it and so cools downs and swells out. Elements from helium to iron are formed.
    - - A huge explosion where all the elements heavier than iron are formed
    - - The star enters a long stable period, which typically lasts several billion years
      - During this period, the outward pressure caused by thermal expansion balances the force of gravity pulling everything inwards
    - - Flung out into space
    - - The force of gravity pulls the gas and dust together to form a protostar.
      - The force of gravity pulls the gas and dust together to form a protostar.
    - - The core collapses into neutron star
    - - Stars initially form from a cloud of dust and gas called nebula.
    - - With enough mass this can become a black hole
- - - - Blue: >11 000
      - blue-white: 7500 - 11 000
      - white: 6000 - 7500
      - yellow-white: 5000 - 6000
      - orange: 3500 – 5000
      - red: < 3500
