Hertzsprung-Russell Diagram

Hertzsprung-Russell Diagram. H-R Diagram. Compares the temperature, color and luminosity (brightness) of stars on a graph. The temperature is the surface temperature of the star. The brightness of the star is its absolute magnitude. APPARENT MAGNITUDE VS. ABSOLUTE MAGNITUDE.

  1. Hertzsprung-Russell Diagram

  2. H-R Diagram • Compares the temperature, color and luminosity (brightness) of stars on a graph. • The temperature is the surface temperature of thestar • The brightness of the star is its absolute magnitude

  3. APPARENT MAGNITUDE VS. ABSOLUTE MAGNITUDE Measure of the amount of a star’s light received on Earth Apparent magnitude Measure of the amount of lighta star actually gives off Absolute magnitude

  4. STAR PROPERTIES Color indicates temperature Hot stars are Blue Cool stars are Red Medium temperature stars are Yellow

  5. White dwarfs small, hot stars leftover centers of old stars

  6. Red-Giants When star runs out of energy, the center shrinks and the outer part expands outward. It will grow very large and cool.

  7. Supergiants Very massive cool giant star

  8. Main Sequence Stretches diagonal from the top left to the right bottom Our sun is an average main sequence star

  9. Blue Supergiants Very massive blue stars Quickly use up energy and turn into Giants or Supergiants

  10. Red Dwarfs Low-mass stars Oldest stars in galaxy

  11. Putting it all together http://www.eram.k12.ny.us/education/sctemp/77f43cfb9ae82b830c63fb080599aa31/hr.swf H-R Diagram AND Life Cycle
