Explain the concept of star death in relation to:
- planetary nebula
- supernovae
- white dwarfs
- neutron stars/pulsars
- black holes
- Eventually, giant stars develop a core of material that cannot be fused, due to either:
- Lack of energy for fusion.
- The core being iron, which will not fuse to produce energy.
- The shells surrounding the core are shed into space, and the core collapses under gravity.
- The way in which this happens depends upon the mass of the star:
