Analyse information from a H-R diagram and use available evidence to determine the characteristics of a star and its evolutionary stage

  • On main – can get approx. mass (further left is more massive)
  • Above main – post main, red giants are above centre to the right and can infer they were sun like, towards top are super giants which are only there for a short time
  • Below main – white dwarf which are final stages
  • Can also read off base characteristics (luminosity, surface temp/colour index/spectral class
