- Use plotted positions to identify hotter, brighter, main-sequence or dwarf stars.
8.12P Hertzsprung-Russell diagram question 1
This question is about stars.
The evolution of stars can be shown on a Hertzsprung-Russell diagram (HR diagram).
Complete the HR diagram by
- labelling the x-axis
- completing the absolute magnitude scale
- drawing the main sequence, red giant and white dwarf regions
