Hertzsprung-Russell Diagram or Characteristics of Stars ESRT PAGE 15 • Stars are classified by luminosity, temperature and size Luminosity • Rate at which star emits energy relative to the SUN How does the temperature read on the diagram? • Temperatures go from high to low or hot to cold What is the luminosity and temperature of Pollux? 90 4500 (K) Find Eridani B. What stage of its life is it in? White Dwarf Deneb is a supergiant at what stage? What will it eventually become? List the following in increasing temperature: Sun, Rigel, Barnard’s Star, Betelgeuse, Sirius Barnard’s Star, Betelgeuse, Sun, Sirius, Rigel
