know that a star’s colour is related to its surface temperature

describe the evolution of stars of similar mass to the Sun through the following stages:

- nebula
- star (main sequence)
- red giant
- white dwarf.

describe the evolution of stars with a mass larger than the Sun

understand how the brightness of a star at a standard distance can be represented using absolute magnitude
