The end of a star

STARS about the SAME SIZE  (or smaller) than THE SUN/ OR LOWER MASS STAR : 

  • Stage 3: RED GIANT
  • at this stage, helium and other light elements= fuses in core to form heavier elements.
  • Stage 4: WHITE DWARF
  • no more light elements left in core= fusion stops and no more radiation is released.
  • due to its own gravity, star COLLAPSES on itself- and heats up from red to yellow to white= becomes a WHITE DWARF.
  • Stage 5: BLACK DWARF
  • stars like the sun fade out, go cold, and become BLACK DWARFS.

STARS MUCH BIGGER THAN THE SUN/ HIGHER MASS STAR:

Use this with the other revision notes 'life history of a star'.

Fantastic revision notes as this topic is something that students can find difficult to comprehend. Very highly recommended. Great use of colour, and highlighting key words is always a good memory technique.
