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:
