Life Cycle of a Star- GCSE Physics P2Watch
Just wondering whether anyone could go through the life cycle of a star for me? Preferably note form.
I just don't...get it?
2) Protostar - gravitational forces pull the particles into a smaller volume, as more particles are pulled in the temperature rises
3) Main sequence star - as the temperature rises, fusion reactions begin to happen
4) Redgiant / Super Red Giant - as the hydrogen in the star is used up, the star contracts. As it contracts, the star heats up - causing it to expand. As it expands, the outer layers cool, making them look red.
FOR BIG STARS
5) As the star runs out of hydrogen, it explodes forming a protostar
6) And then it can either:
a) Neutron Star - when only the centre of the star remains
b) Black hole - If the star collapses on itself it forms a black hole
OR FOR SMALL STARS
5) White dwarf -As the star contracts again, it heats up, and becomes a white dwarf
6) Black dwarf - As the star is no longer able to sustain any further fusion reactions, it fades
This is from memory, and may be incorrect in areas
