The white dwarf stage is reached when a star has used up all its fuel and is radiating away its remaining thermal energy as light. Red giant is a stage where a low-mass star expands and becomes red as hydrogen fuel in the core runs out. Black dwarf is a theoretical stage when a white dwarf cools down and stops emitting light. Black hole is a stage when a massive star collapses under its own weight and forms an object with such strong gravity that nothing can escape from it.
